Question

multiple choice question

which of the following couples (links) anabolic reactions with catabolic reactions?

enzymes
atp
substrates
glucose
amp

Explanation:

Define metabolic coupling

$$ \text{Catabolism (exergonic)} \longrightarrow \text{Energy (ATP)} \longrightarrow \text{Anabolism (endergonic)} $$

Identify the energy carrier

$$ \text{Catabolic reactions release energy stored as ATP.} $$

$$ \text{Anabolic reactions consume ATP to synthesize complex molecules.} $$

Evaluate the given options

$$ \text{ATP directly links catabolism and anabolism by transferring chemical energy.} $$

Answer:

• Enzymes
• ATP (Correct answer)
• Substrates
• Glucose
• AMP
