BIOMOLECULES AND ENZYMES

Detailed explanation-1: -A fundamental task of proteins is to act as enzymes-catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.

Detailed explanation-2: -Some proteins function as enzymes, i.e., proteins that catalyze specific biochemical reactions. Enzymes facilitate biochemical reactions and speed them up enormously, making them as much as a million times faster. There are thousands of enzymes, and each type facilitates a specific biochemical reaction.

Detailed explanation-3: -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.

Detailed explanation-4: -Definition. An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell.
