What are enzymes and what do they have to do with metabolism?

Answer 1

Enzymes are chemicals in saliva, or spit, that break down your food so that you can digest it. Without enzymes, you wouldn't be able to digest your food.

Enzymes are known as biological catalysts as they lower the energy barrier and so speed up the reaction without being used up in that reaction. Enzymes are made up of proteins and the effectiveness of their actions is changed by changing temperature or pH or by chamicaly changin the molecule. Metabolic pathways are how the body makes many of the things it needs, they involve many breakdowns and rebuilds of substnaced and these changes are made possible because of the presence of enzymes.

Answer 2

Enzymes are protein molecules, produced by living cells, that function as catalysts of biochemical reactions. Without enzymes, living cells would not be able to perform the chemical reactions needed for their metabolism.

Answer 3

Enzymes are biological molecules that catalyze or increase the rates of chemical reactions. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. There are many of these, but enzymes are known to catalyze about 4,000 biochemical (life) reactions.

Answer 4

Enzymes are biological molecules that act as catalysts in speeding up chemical reactions in cells. In metabolism, enzymes play a crucial role in breaking down food molecules to release energy and building blocks for cells to function properly. They are essential for regulating and maintaining various metabolic pathways in the body.
