As protons flow back into the mitochondrial matrix through ATP synthase, energy is harnessed. Where is the highest concentration of protons maintained during respiration?
Q1. As protons flow back into the mitochondrial matrix through ATP synthase, energy is harnessed. Where is the highest concentration of protons maintained during respiration?
Answer: Intermembrane space
Explanation: Protons are pumped into the intermembrane space, creating a gradient; the matrix has a lower proton concentration during active transport.
