A chemical blocks ATP synthase. The immediate consequence is
A.protons accumulate and electron transport stalls
B.electron transport speeds up
C.glycolysis stops instantly
D.oxygen production begins
Explanation
Core Concept
With the H⁺ channel blocked, the gradient cannot dissipate; backpressure eventually halts pumping and electron flow, so NADH stops being oxidized.
Correct Answer
Aprotons accumulate and electron transport stalls
