Question

multiple choice question

typically, each reaction (step) in a metabolic pathway will require ______.

several cofactors
one enzyme
several substrates

Explanation:

Analyze metabolic pathway characteristics

$$ \text{Metabolic Pathway} = \text{Step}_1 \xrightarrow{\text{Enzyme}_1} \text{Step}_2 \xrightarrow{\text{Enzyme}_2} \dots \xrightarrow{\text{Enzyme}_n} \text{Product} $$

Evaluate the role of enzymes in individual steps

$$ \text{Each individual step (reaction)} \implies \text{Catalyzed by exactly one specific enzyme} $$

Answer:

• several cofactors
• one enzyme (Correct answer)
• several substrates
