Description: but we have a solution. Here you see actually how the damage appears in this material. It's a porous asphalt, like I said, so you have only a small amount of binder between the stones. Due to weathering, due to U.V. light, due to oxidation, this binder, this bitumen, the glue between the aggregates is going to shrink,

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.

American Scientist

John E. Walker

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.

English Scientist

Joel Fuhrman

Hypertension is an important risk factor for kidney disease, but dietary sodium has other damaging effects on the kidneys. High salt intake drives the production of oxygen radicals, leading to oxidative stress in kidney tissue.

Albert Szent-Gyorgyi

So I set out to study the oxidation system in the potato, which, if damaged, causes the plant to turn brown. I did this in the hope of discovering, through these studies, the key to the understanding of adrenal function.

Hungarian Scientist

Luis Federico Leloir

We managed to prepare a cell-free system which was active when suitably supplemented, and this was a novel result since the process of oxidation was believed to require the integrity of the cells.

French Scientist

John Simon

Activating oxygen can produce compounds called radicals that put oxidative stress on cells. Such stress could ultimately lead to cancer and other diseases.

Critic

Otto Heinrich Warburg

Catalytic oxidation in living substances rests upon change of valency in an iron compound which is the respiratory oxygen-transferring ferment.

German Scientist

After returning from Cambridge in 1936, I did some work with J. M. Mioz on the oxidation of fatty acids in liver.

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

Oxidation often causes observable changes like color alteration or corrosion.

Visible Changes

Use common instances such as rust and tarnishing to explain oxidation in daily life.

Everyday Examples

Explain that oxidation can be an exothermic reaction releasing heat or light.

Energy Release

Clarify that losing electrons is key and not necessarily involving oxygen in modern chemistry.

Electron Loss

Highlight that oxidation is often paired with reduction, together known as redox reactions.

Redox Pairing

Explain oxidation state as an atom's apparent charge due to electron gain or loss.

Oxidation State

Discuss the role of antioxidants in combating harmful oxidation in the body.

Health Implications

Underline the production of free radicals during oxidation in the body's cells.

Free Radical Awareness

Identify cellular damage as a consequence of uncontrolled oxidation, leading to diseases.

 that drives the reaction to regenerate the metal, making more electrons available for oxidation the next time you need them. But even rechargeable batteries don't last forever. Over time, the repetition of this process causes imperfections
