Which of the following best describes the fundamental principle of chemiosmosis as an energy-coupling mechanism?
A: It involves the direct transfer of energy from glucose oxidation to ATP synthesis.
B: It uses energy stored in an H+ gradient across a membrane to drive cellular work, such as ATP synthesis.
C: It is a process where ATP is directly generated by redox reactions in the electron transport chain.
D: It describes the movement of glucose across the cell membrane driven by proton pumps.
Explanation
Chemiosmosis is defined as an energy-coupling mechanism that uses energy stored in the form of an H+ gradient across a membrane to drive cellular work, such as ATP synthesis, as stated in the text.
