Question

An example of destructive metabolism (catabolism) is

• A. Photosynthesis
• B. Respiration
• C. Glycogenesis
• D. Both B and C

Answer 1

The correct option is B Respiration

Destructive metabolism is the breakdown of more complex substances into simpler ones with release of energy.

And Respiration is concerned with the release of energy from the oxidation of complex organic compounds.

so technically respiration is a type of Catabolism.

While the other two are anabolic because in both the process substances are synthesised and used in the body.
