BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Proteins are responsible for nearly every task of cellular life, including cell shape and inner organization, product manufacture and waste cleanup, and routine maintenance. Proteins also receive signals from outside the cell and mobilize intracellular response.

Detailed explanation-2: -Every cell in the human body contains protein. The basic structure of protein is a chain of amino acids. You need protein in your diet to help your body repair cells and make new ones. Protein is also important for growth and development in children, teens, and pregnant women.

Detailed explanation-3: -Explanation: catalysing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules from one location to another.

Detailed explanation-4: -Proteins serve many functions in cells. They act as enzymes that catalyze chemical reactions, provide structural support, regulate the passage of substances across the cell membrane, protect against disease, and coordinate cell signaling pathways.
