• A. Hydrolysis for energy provision.
• B. Structural integrity of the cell.
• C. Regulation of metabolism.
• D. Defense mechanisms.

Answer 1

The correct option is A Hydrolysis for energy provision.

Proteins are the most important and versatile biomolecules in living systems. They are involved in general body-building, catalytic role as enzymes, and body defence in immunological reactions. Energy currency of living systems are usually nucleotides like ATP. They are hydrolysed to provide energy as and when required.
