Mitochondria Quotes

We are each of us the result of billions of years of the universe evolving toward its own splendor. And evolution builds: the very mitochondria that power our cells and give us life once existed as separate organisms that first infected our pre–pre–human ancestors and then became one with them. We each contain not only the slime mold and the worm, the fish and amphibian and reptile, but the pig and the ape and the barely human. If we look hard enough, we can discern hundreds of parts: kings and queens, warriors and troubadours, mages, bullies, and saints. And hustlers, adventurers, survivors, rebels, reactionaries, and rogues. And the part of us that wants to be more than human, or rather more fully human. I believe that we need to enlist all these separate selves into a single army of free companions who respect each other and love each other to the death. And who are willing to devote their lives to fight together in order to win a shared splendor.
I will return to this theme of integration again and again, for it is key to everything. All of my characters struggle with themselves, and face as well external obstacles such as exploding stars or dragons or icy wastelands cold enough to freeze the breath. Maram, who writes poems glorifying his second chakra (the body's sexual center), pants like a dog after every enticing woman he sees. Even as he resists his essential nobility and destiny as a hero, he insists that every man deserves at least one vice. When it is pointed ~ David Zindell

Over the long term, symbiosis is more useful than parasitism. More fun, too. Ask any mitochondria. ~ Larry Wall

Mitochondria, as we have seen, are only passed on in the egg, so all 13 mitochondrial genes come from our mothers. If these genes really do influence lifespan, and we can only inherit them from our mothers, then our own lifespan should reflect that of our mothers but not our fathers. ~ Nick Lane

Rather surprisingly, to anyone who is most familiar with textbook mitochondria, many simple single-celled eukaryotes have mitochondria that operate in the absence of oxygen. Instead of using oxygen to burn up food, these 'anaerobic' mitochondria use other simple compounds like nitrate or nitrite. In most other respects, they operate in a very similar fashion to our own mitochondria, and are unquestionably related. So the spectrum stretches from aerobic mitochondria like our own, which are dependent on oxygen, through 'anaerobic' mitochondria, which prefer to use other molecules like nitrates, to the hydrogenosomes, which work rather differently but are still related. ~ Nick Lane

Power, Sex, Suicide: Mitochondria and the Meaning of Life. Oxford: ~ Gary L. Wenk

Were it not for the melanin in our skin, myoglobin in our muscles and haemoglobin in our blood, we would be the colour of mitochondria. And, if this were so, we would change colour when we exercised or ran out of breath, so that you could tell how energized someone was from his or her colour. ~ Guy Brown

When the stars imploded billions of years ago, iron and silver, gold and carbon came raining down. And the iron from that stardust is in us today-in our mitochondria. Mothers pass on the stars and their iron to their children. Who knows, Jean, you and I might be made of the dust from one and the same star, and maybe we recognized each other by its light. We were searching for each other. We are star seekers. ~ Nina George

Indeed, Dr. Cahill and other researchers have determined that beta-HBA, which is easily obtainable just by adding coconut oil to your diet, improves antioxidant function, increases the number of mitochondria, and stimulates the growth of new brain cells. In chapter 5 we ~ David Perlmutter

Although separating mitochondria and microsomes might appear worlds apart from the determination of the molecular weight of macromolecules, certain concepts were common to the two operations and could be usefully transposed from the latter to the former. ~ Christian De Duve

I knew the lysosomes and peroxisomes because I had discovered them; I knew the mitochondria because I was interested in them. I knew the membrane system because my friend, George Palade, had worked on that. ~ Christian De Duve

Metabolically active cells, such as those of the liver, kidneys, muscles, and brain, have hundreds or thousands of mitochondria, making up some 40 per cent of the cytoplasm. The egg cell, or oocyte, is exceptional: it passes on around 100000 mitochondria to the next generation. In contrast, blood cells and skin cells have very few, or none at all; sperm usually have fewer than 100. All in all, there are said to be 10 million billion mitochondria in an adult human, which together constitute about 10 per cent of our body weight. ~ Nick Lane

school you may have learned the basic components of a cell: the nucleus that contains genetic material, the energy-producing mitochondria, the protective membrane at the outside rim, and the cytoplasm in between. ~ Bruce H. Lipton

the greatest mutational health hazard in the population is fertile old men. Thankfully, uniparental inheritance means that men don't pass on their mitochondria at all. ~ Nick Lane

We are not made up, as we had always supposed, of successively enriched packets of our own parts. We are shared, rented, occupied. At the interior of our cells, driving them, providing the oxidative energy that sends us out for the improvement of each shining day, are the mitochondria, and in a strict sense they are not ours. ~ Lewis Thomas

In the artifacts that are conscious, memories of vanished lives still flicker. Tissues that were changed without dying hold the moment that a boy heard his sister was leaving home. They hold multiplication tables. They hold images of sexuality and violence and beauty. They hold the memories of flesh that no longer exists. They hold metaphors: mitochondria, starfish, Hitler's-brain-in-a-jar, hell realm. They dream. Structures that were neurons twitch and loop and burn and dream. Images and words and pain and fear, endless. ~ James S.A. Corey

Optimism

More and more I have come to admire resilience.
Not the simple resistance of a pillow, whose foam
returns over and over to the same shape, but the sinuous
tenacity of a tree: finding the light newly blocked on one side,
it turns in another. A blind intelligence, true.
But out of such persistence arose turtles, rivers,
mitochondria, figs - all this resinous, unretractable earth. ~ Jane Hirshfield

Sperm pass on none of their mitochondria during conception, so all mitochondrial information is transferred from generation to generation through mothers alone. Such a system means that there will be many extinctions along the way. A woman endows all her children with her mitochondria, but only her daughters have the mechanism to pass it onward to future generations. So if a woman has only sons or no children at all - and that happens quite often, of course - her personal mitochondrial line will die with her. All her descendants will still have mitochondria, but it will come from other mothers on other genetic lines. In consequence, the human mitochondrial pool shrinks a little with every generation because of these localized extinctions. Over time, the mitochondrial pool for humans has shrunk so much that, almost unbelievably but rather wonderfully, we are all now descended from a single mitochondrial ancestor - a woman who lived in Africa about 200,000 years ago. You might have heard her referred to as Mitochondrial Eve. She is, in a sense, mother of us all. ~ Bill Bryson

This is the mitochondrial DNA." Bowers nodded back to the cryo-case. "It's the genetic material that actually makes the energy that powers our cells. Think of it like this. Each of our cells has the usual 23 pairs of chromosomes that make us human and determine our physical appearance, how we fight off disease, and other physical characteristics. Now think of the mitochondria as little organisms within our cells. Like cells within a cell. It's those little organisms that make energy for our cells. And they have their own DNA." "I ~ Jonathan Brookes

The sheer mystery and majesty of heritage wisdom, contained in each cell, each mitochondria, instills in the farmer who respects and honors the pigness of the pig a daily emotional high. The satisfaction of being nature's nurturer always trumps the short-lived adrenaline high of being nature's conqueror. Such an attitude offers spiritual ascendance over physical domination, which never really happens anyway. And that's why the industrial farmer, for all the smoke and noise and horsepower, never feels in control, but always dreads being drowned by the nature he thinks he's controlling. ~ Joel Salatin

Glyphosate also interferes with ATP production by affecting your mitochondrial membranes. When coupled with the so-called inert solvents included in Roundup, the toxicity of glyphosate is magnified as much as 2,000-fold. This makes the membrane more permeable, allowing the glyphosate to go straight to the heart of the mitochondria. ~ Joseph Mercola

mitochondria and the ribosomes and the chloroplasts and the endoplasmic reticulum. ~ Belle Payton

This was difficult to prove as most hydrogenosomes have lost their entire genome, but it is now established with some certainty.1 In other words, whatever bacteria entered into a symbiotic relationship in the first eukaryotic cell, its descendents numbered among them both mitochondria and hydrogenosomes. ~ Nick Lane

Mitochondrial genes act like a female surname, which enables us to trace our ancestry down the female line in the way some families try to trace their descent down the male line from William the Conqueror, or Noah, or Mohammed. ~ Nick Lane

My mitochondria comprise a very large proportion of me. I cannot do the calculation, but I suppose there is almost as much of them in sheer dry bulk as there is the rest of me. Looked at in this way, I could be taken for a very large, motile colony of respiring bacteria, operating a complex system of nuclei, microtubules, and neurons for the pleasure and sustenance of their families, and running, at the moment, a typewriter. ~ Lewis Thomas

A team from Sydney, Australia, has lowered levels of these proteins using light. They implanted human genes associated with Alzheimer's into mouse DNA, so that the animals developed abnormal tau proteins and amyloid plaques. Then they treated them for a month with low-level light therapy, simply by holding the light one to two centimeters above the animals' heads. Using the same spectrum of near-infrared light that has helped in traumatic brain injury, Parkinson's disease, and retinal damage, they lowered both the pathological tau proteins and the amyloid plaques by 70 percent in key brain areas that Alzheimer's affects. Thereafter signs of "rusting" decreased, and the mitochondria, the powerhouses of the cells, improved their function. ~ Norman Doidge

This was it. Kiyomi realized it now. This was what her heart had reacted to. Her heart thrilled to mitochondria.
But why? ~ Hideaki Sena
