The Nobel Prize in Chemistry 1992 was awarded to Rudolph A. Marcus for his contributions to the theory of electron transfer reactions in chemical systems.
Enzymes decrease the amount of activation energy required for chemical reactions to occur.
Biochemistry is the study of chemical reactions in living systems. An example of a biochemical process would be fermentation: Glucose (C6H12O6) breaks down in the presence of zymase (enzyme) and the waste product is ethanol (CH3CH2OH or C2H5OH) and carbon dioxide(CO2). gross to think about - the alcohol we drink is a waste product.
The most common way to speed up chemical reactions in non-living systems is to add heat. Heat causes the molecules to move faster, creating more collisions. In some reactions, extra oxygen is used to speed them up.
Biological catalysts are called enzymes. All enzymes are globular proteins, and speed up metabolic reactions in our bodies.

Chemical reactions are described based on observations. It may be in terms of changes in color, state of matter, or density.
Some chemical reactions that happen in living systems can not, do not occur outside of living organisms., Natural product chemistry is regio, and steroslective. Nature produces only one of the possble 256 "mirror image" isomers of cholesterol. Try this in a lab from scrath and you can get a mix of 256 isomers, 255 which you do NOT want.
That is the question we must ALL ask ourselves. What is the conclusion of our life? Is there a conclusion? Or is it just some kind of perceptual illusion of imagery where anything can happen and it's all played out by a series of events. Our human body is composed of organ systems that perform chemical reactions every day. But when the human body dies, it is the conclusion of the life and chemical reactions are made no longer.

In biological systems an enzyme speeds up the reaction without changing it. In other chemical reactions this function is achieved by a catalyst.
This substance is called catalyst; and in living systems it is an enzyme.
Products may take many years to form.
