66. An experimental uncoupling agent that renders the inner mitochondrial membrane leaky to protons (H+) would cause a direct increase in

A. ATP synthesis output
B. Heat generation and oxygen consumption
✓
C. Proton gradient intensity
D. Matrix pH levels

📝 Explanation

Uncouplers dissipate the proton gradient without making ATP. Energy is lost as heat, driving the cell to burn oxygen faster to compensate.

📖 Additional Information

  • ATP synthesis output
  • Heat generation and oxygen consumption
  • Proton gradient intensity
  • Matrix pH levels

Uncouplers dissipate the proton gradient without making ATP. Energy is lost as heat, driving the cell to burn oxygen faster to compensate.
