Osmosis describes the movement of water across a biological membrane and down its concentration gradient.In chemiosmosis, useful energy is harnessed by the cell from the movement of __________ across the inner mitochondrial membrane into the matrix __________ a concentration gradient.

Question

Quizplus · Accepted Answer

Chemiosmosis involves the movement of protons (H+) across the inner mitochondrial membrane into the matrix down a concentration gradient, which is then used to generate ATP through the action of ATP synthase. None of the other options accurately describe this process.
