Question

1. what is the term that describes a collection of metabolic reactions necessary for the survival of living cells?

anabolism
metabolism
photosynthesis
respiration

Explanation:

• Anabolism only refers to the metabolic reactions that build complex molecules, not all necessary reactions.
• Metabolism encompasses all the catabolic (breaking down) and anabolic (building up) reactions that sustain living cells.
• Photosynthesis is a specific metabolic reaction limited to autotrophs, producing glucose from light energy, not all survival reactions.
• Respiration is a specific catabolic reaction that breaks down glucose for energy, not all necessary cellular metabolic reactions.

Answer:

metabolism
