Question

Which one of the following is an anabolic process?

• A. Photosynthesis
• B. Digestion
• C. Excretion
• D. Respiration

Answer 1

Answer: (A)

Anabolic processes are reactions in which smaller organic molecules are used for the production of the large complex molecules. The process is an endergonic process in which the energy is supplied for the formation of the new bonds in the larger complexes. In the process of photosynthesis, the smaller carbon dioxide molecules are fixed for the formation of the six-carbon glucose molecule. This is building reaction which is a type of anabolic reaction.

Thus, the correct answer is option D.
