Cellular Respiration Quotes

I remember, as a boy of 17 years of age, this was a fascinating thing for me: how we human beings breathe out carbon dioxide into the air, the leaves of plants pick this carbon dioxide up, and the plant gives off oxygen, which we can breathe in and keep our life going.

Many years ago it was taught that plants and animals were composed of different materials: plants, of a chemical substance of three elements,- carbon, hydrogen, and oxygen; animals of one of four elements, nitrogen being added to the other three.

You do not explain the tree by telling of the water it has drunk, the minerals it has absorbed, and the sunlight that strengthened it.

This oxidation of hydrogen in stages seems to be one of the basic principles of biological oxidation.

The blood corpuscles take up the atmospheric oxygen in the lungs, and the vital chemical process accordingly depends essentially on the combination of oxygen absorbed by blood corpuscles with the combustible constituents of the blood to form carbonic acid and water.

By 'life,' we mean a thing that can nourish itself and grow and decay.

When you think about the complexity of our natural world - plants using quantum mechanics for photosynthesis, for example - a smartphone begins to look like a pretty dumb object.

The cell, over the billions of years of her life, has covered the earth many times with her substance, found ways to control herself and her environment, and insure her survival.

The toxic effect of carbon monoxide on man has nothing to do with inhibition of cellular respiration by carbon monoxide but is based on the reaction of carbon monoxide with blood iron.

For a very long time, we've been extraordinarily interested in the interaction between low temperature and low oxygen. We see that they're connected because we know people who are extremely cold are not getting oxygen to their cells. And yet, they're sometimes alive.

If I could remember the names of all these particles, I'd be a botanist.

Our cells engage in protein production, and many of those proteins are enzymes responsible for the chemistry of life.

We finally understand in general terms how a cell is organized, how its specialized organs function in a well integrated manner to insure its survival and replication.

We are seeing the cells of plants and animals more and more clearly as chemical factories, where the various products are manufactured in separate workshops.

He gave life to the breath- oxygen, a simple gas, he transferred into words, ideas, hope.

A living cell requires energy not only for all its functions, but also for the maintenance of its structure.

Biochemistry is the science of life. All our life processes - walking, talking, moving, feeding - are essentially chemical reactions. So biochemistry is actually the chemistry of life, and it's supremely interesting.

Next it was found that it was physiologically and structurally the same in the plant, that it was the living part of the plant, that which manifested the life and did the work in vegetable as well as in animal organisms.

Life exists in the universe only because the carbon atom possesses certain exceptional properties.

Since it is the very substance of the animal, it is the blood which transports the fuel.If the animal did not habitually replace, through nourishing themselves,what they losethrough respiration, the lamp would very soon run out of oil and the animal would perish, just as the lamp goes out when it lacks fuel.

Muscles do not use oxygen at a constant rate.

And let me adde, that he that throughly understands the nature of Ferments and Fermentations, shall probably be much better able than he that Ignores them, to give a fair account of divers Phænomena of severall diseases (as well Feavers and others) which will perhaps be never throughly understood, without an insight into the doctrine of Fermentation.

Proteins are the machinery of living tissue that builds the structures and carries out the chemical reactions necessary for life.

Biological energy comes from the sun. Light energy harvested by photosynthesis in chloroplasts and phototropic bacteria becomes stored in carbohydrates and fats. This stored energy can be released by oxidative metabolism in the form of adenosine triphosphate (ATP) and used as fuel for other biological processes.

In trees, I see expression and soul
