Question 6 WAEC_MODEL_QUESTIONS_VOL1 • 2017 • BIOLOGY • objective

A toxin that specifically inhibits the enzyme ATP synthase is introduced into a eukaryotic cell. As a result, aerobic respiration efficiency drops dramatically. Identify the organelle that contains ATP synthase and explain why inhibition of this enzyme reduces ATP production.

Answer Options

A. Nucleus; inhibition stops the proton‑driven synthesis of ATP by ATP synthase, so ATP production falls dramatically.
B. Chloroplast; inhibition stops the proton‑driven synthesis of ATP by ATP synthase, so ATP production falls dramatically.
Correct Answer C. Mitochondrion; inhibition stops the proton‑driven synthesis of ATP by ATP synthase, so ATP production falls dramatically.
D. Endoplasmic reticulum; inhibition stops the proton‑driven synthesis of ATP by ATP synthase, so ATP production falls dramatically.
Correct Answer
C
Correct Option:
Mitochondrion; inhibition stops the proton‑driven synthesis of ATP by ATP synthase, so ATP production falls dramatically.
