Question

Respiration is a/an …………. process.

• A. Anabolic
• B. Catabolic
• C. Metabolic
• D. None

Answer 1

The correct option is B

Catabolic

The correct option is (B)

Explanation for the correct option:

1. Respiration is a process by which oxidation of food/glucose occurs in the cells leading to the release of carbon dioxide and energy.
2. In this process, complex molecules like glucose are broken down into simpler molecules like carbon dioxide and water.
3. Catabolic processes are those processes in which the breakdown of complex molecules into simpler molecules occurs for the release of energy.
4. Respiration is a catabolic process.

Explanation for the incorrect options:

Option (A):

1. Anabolic processes are those processes in which complex molecules are synthesized from simpler molecules.
2. An example of an anabolic process is photosynthesis.

Option (C):

1. Metabolic processes are defined as those processes which are responsible for the maintenance of living conditions inside the cells.

Final answer: Respiration is a catabolic process.
