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: -Enzymes are substances found in biological systems that are catalysts for specific biochemical processes.

Detailed explanation-3: -Biocatalysis is defined as the use of natural substances that include enzymes from biological sources or whole cells to speed up chemical reactions. Enzymes have pivotal role in the catalysis of hundreds of reactions that include production of alcohols from fermentation and cheese by breakdown of milk proteins.

Detailed explanation-4: -Enzymes are biological catalysts. They speed up biochemical reactions. Enzymes are proteins that catalyze biochemical reactions. A catalyst is a chemical that speeds up chemical reactions.

Detailed explanation-5: -Enzymes are proteins that act as catalysts in biochemical reactions. Common types of catalysts include enzymes, acid-base catalysts, and heterogeneous (or surface) catalysts.
