NEET BIOLOGY

Detailed explanation-1: -Proteins play a crucial role in the human body. These complex molecules help maintain the structure and function of organs and tissue, regulating cellular activity at the most fundamental level.

Detailed explanation-2: -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-3: -The answer is enzymes. Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction. Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits.

Detailed explanation-4: -A protein can control the rate of reaction and regulate the cell processes, and from crucial cellular structures or transport substances out or into cells to help battle a disease.
