NURSING ANM AND GNM

Detailed explanation-1: -Enzymes are proteins that act upon substrate molecules and decrease the activation energy necessary for a chemical reaction to occur by stabilizing the transition state. This stabilization speeds up reaction rates and makes them happen at physiologically significant rates.

Detailed explanation-2: -Which of the following is classified as an enzyme? The correct answer is c. protease.

Detailed explanation-3: -Enzymes are classified into six categories according to the type of reaction catalyzed: Oxidoreductases, transferases, hydrolases, lyases, ligases, and isomerases. Structurally, the vast majority of enzymes are proteins.
