Question

Which among the following is an example of catabolism?

• A. Respiration
• B. Photosynthesis
• C. Glycogenesis
• D. Both b) and c)

Answer 1

The correct option is A Respiration

Catabolism is the breakdown of complex substances into simple particles releasing energy. In aerobic respiration, the carbohydrate (glucose) gets broken down releasing energy in the form of ATP.

Anabolism is the process of building up complex organic compounds from simple inorganic compounds using energy.

Photosynthesis is an anabolic pathway. In Photosynthesis, using $C{O}_2$ and water, in the presence of sunlight using chlorophyll, green plants are able to synthesize a carbohydrate. During this process energy is used.

Glycogenesis is synthesis of glycogen.
