BIOMOLECULES AND ENZYMES

Detailed explanation-1: -This is the case for the large and very important class of proteins called enzymes. As described in Chapter 2, enzymes are remarkable molecules that determine all the chemical transformations that make and break covalent bonds in cells.

Detailed explanation-2: -Enzymes are proteins that act as catalysts.

Detailed explanation-3: -Enzymes act as catalysts for metabolic reactions. Enzymes are proteins that are specific for particular reactions. The standard suffix for enzymes is “ase, ” so it is easy to identify enzymes that use this ending (although some do not). The substance on which the enzyme acts is called the substrate.

Detailed explanation-4: -Enzymes. Enzymes are proteins that catalyze biochemical reactions, which otherwise would not take place. These enzymes are essential for chemical processes like digestion and cellular metabolism. Without enzymes, most physiological processes would proceed so slowly (or not at all) that life could not exist.

Detailed explanation-5: -Example: Protease is an enzyme that helps in the breakdown of protein.
