Quotes About Cells

Neurons are living cells with a metabolism. And they need glucose in order to function. Glucose is the fuel of the brain, just like gasoline is the fuel of your car.

Your brain is built of cells called neurons and glia - hundreds of billions of them. Each one of these cells is as complicated as a city.

Buchner proposed that fermentation was carried out by biological catalysts that he named enzymes (from the Greek en zyme, meaning in yeast). He concluded that living cells are chemical factories, in which enzymes manufacture the various products.

Well, biology is not only about genes and environment, but also cells and the constraints of their physical structure, which we shall see have little to do with either genes or environment directly. The predictions that arise from these disparate world views are strikingly different.

it's no mystery that all cells here on earth should be chemiosmotic. I would expect that cells across the universe will be chemiosmotic too.

One mitochondrion contains tens of thousands of copies of each respiratory complex. A single cell contains hundreds or thousands of mitochondria. Your 40 trillion cells contain at least a quadrillion mitochondria, with a combined convoluted surface area of about 14,000 square metres; about four football fields. Their job is to pump protons, and together they pump more than 1021 of them – nearly as many as there are stars in the known universe – every second.

So it seems to me there are two big unknowns at the very heart of biology today: why life evolved in the perplexing way it did, and why cells are powered in such a peculiar fashion. This

The environment most realistically capable of giving rise to life, whether here or anywhere else in the universe, is alkaline hydrothermal vents. Such vents constrain cells to make use of natural proton gradients, and ultimately to generate their own.

There isn't any real you in you, she says, Even your physical body, all your cells will be replaced within eight years.

I knew—but I did know that I had crossed 700  The border. Everything I loved was lost But no aorta could report regret. A sun of rubber was convulsed and set; And blood-black nothingness began to spin A system of cells interlinked within Cells interlinked within cells interlinked Within one stem. And dreadfully distinct Against the dark, a tall white fountain played. I

I can't tell you how I knew - but I did know that I had crossed The border. Everything I loved was lost But no aorta could report regret. A sun of rubber was convulsed and set; And blood-black nothingness began to spin A system of cells interlinked within Cells interlinked within cells interlinked Within one stem. And dreadfully distinct Against the dark, a tall white fountain played.

A system of cells interlinked within Cells interlinked within cells interlinked Within one stem. And dreadfully distinct Against the dark, a tall white fountain played.

Mr. McCleod: And if there's anything I want you guys to take with you from this class, as you're abusing your bodies over break, is three things: the heart is the body's strongest muscle, that the brain has more cells in it than our galaxy has stars, and that the body is 72% water. So wherever you go over vacation, don't get too dehydrated.

I looked up "skin" in the encyclopedia and confirmed that, sure enough, it is the human body's largest organ, a fact that suggests our surfaces are critical to who we are, not just the gateway to physical or spiritual depths but a profoundly important web of cells that, in protecting us, gives us form and function.

The goal of the Sufi is not to destroy his or her body, but to awaken each cell to Blessed Awareness of the One Living Truth.

I am God to the cells that compose me.

Life is a whim of several billion cells to be you for a while

The worst part is when cells feel so threatened by their chemically marinated surroundings, that they decide to mutate as a defensive mechanism, and start to reproduce without taking their immediate surroundings into account. This mutation is called cancer.

The best standardisation committee in the world is nature herself, but in nature standardisation occurs mainly in connection with the smallest possible units: cells. The result is millions of flexible combinations in which one never encounters the stereotyped.

We have 200 trillion cells, and the outcome of each of them is almost 100 percent genetically determined. And that's what our experiment with the first synthetic genome proves, at least in the case of really simple bacteria. It's the interactions of all those separate genetic units that give us the physiology that we see.

What I see in science is a lot of imagination referring to things that are fundamental to what we are. Our cells, our history, our future, our place in the universe, our lack of place in the universe. That's poetry as far as I'm concerned.

Cancer is really a DNA disease... We have these certain genes that prevent our cells from growing out of control at the expense of the body. And it's a pretty good, robust system. But if a couple of these genes fail, then that's when cancer starts, and cells start growing out of control.

When a pregnancy begins, those cells begin their mitosis, and during the first three months, everything from limbs to organs to the brain and neurological system is being developed, and I never realized that would consume so much energy: it drains every bit of energy you have, and your hormonal status is changed dramatically!

Cancer cells have a lot of other things that are really wrong with them, and we should never forget that these are cells that have become deaf to all the signals that the body sends out, such as you can multiply a certain amount, you can be in a certain place in the body, where to stay, where to move, and so on.
