Short Answer
The study of biomolecules and metabolism explains life processes by showing how chemical substances and reactions control all activities of living organisms. Biomolecules form the structure of cells, while metabolism provides energy and materials needed for life.
By understanding biomolecules and metabolic reactions, we can explain how organisms grow, move, reproduce, respond to stimuli, and maintain balance. Thus, life processes are best understood at the molecular and metabolic level.
Detailed Explanation :
Biomolecules and Metabolism in Life Processes
Life processes are all the activities that keep an organism alive, such as nutrition, respiration, growth, movement, repair, excretion, and reproduction. These processes may appear complex, but at the basic level, they are controlled by biomolecules and metabolic reactions. The study of biomolecules and metabolism helps us understand how life works inside cells.
Biomolecules are organic molecules present in living organisms, including carbohydrates, proteins, lipids, nucleic acids, enzymes, hormones, vitamins, and minerals. Metabolism refers to all chemical reactions that involve these biomolecules inside cells. Together, biomolecules provide structure and materials, while metabolism provides energy and regulation. This combined study explains every life process scientifically.
