Question

Metabolism includes the processes of catabolism and anabolism. Select the anabolic process(es).

• A. Growth
• B. Storage
• C. Respiration
• D. Excretion

Hint:

Anabolism builds up; catabolism breaks down.

Answer 1

The Correct Option is A, B

In order to determine which processes are anabolic, let's first understand the difference between anabolic and catabolic processes:

• Anabolic Processes: These involve the synthesis of complex molecules from simpler ones. They are energy-consuming processes as they build larger molecules necessary for growth and storage. Examples include protein synthesis and photosynthesis.
• Catabolic Processes: In contrast, these involve the breakdown of complex molecules into simpler ones, releasing energy. Examples include respiration and digestion.

Now, let's analyze the options given:

1. Growth: This is a classic example of an anabolic process, as it involves the construction of complex tissues and cellular structures from simpler molecules. Thus, Growth is an anabolic process.
2. Storage: This process involves the synthesis of compounds like glycogen or fat, where energy is stored in the form of chemical bonds. Therefore, Storage is also an anabolic process.
3. Respiration: It is a catabolic process since it involves breaking down glucose to release energy.
4. Excretion: This is the process of removing waste from the body, and it does not involve the synthesis of new molecules. Hence, it is not anabolic.

Based on the above explanation, the correct anabolic processes from the given options are:

• Growth
• Storage
