Question

multiple choice question

the term \metabolism\ includes which type(s) of cellular reactions?

neither catabolic nor anabolic
catabolic only
anabolic only
both anabolic and catabolic

Explanation:

Define metabolism

Metabolism refers to the sum of all chemical reactions that occur within a living cell or organism to maintain life.

Identify metabolic reaction types

These chemical reactions are broadly divided into two main categories:

1. Anabolism: Reactions that build larger molecules from smaller units, requiring energy.
2. Catabolism: Reactions that break down larger molecules into smaller units, releasing energy.

Determine the correct option

Since metabolism encompasses both the synthesis (anabolic) and breakdown (catabolic) pathways, it includes both anabolic and catabolic reactions.

Answer:

• Neither catabolic nor anabolic
• Catabolic only
• Anabolic only
• Both anabolic and catabolic (Correct answer)
