Which of These Best Describes Chemiosmosis

Question

Which of these best describes chemiosmosis?
A)The movement of water across a biological membrane into or out of a cell.
B)The movement of protons across a biological membrane for energy production.
C)The movement of organic nutrients across a biological membrane into or out of a cell.
D)The movement of inorganic nutrients across a biological membrane into or out of a cell.
E)The production of energy as a result of the reactions occurring in the glycolytic pathway.

Accepted Answer

Chemiosmosis refers to the movement of ions, usually protons, across a biological membrane to generate ATP. This process occurs during oxidative phosphorylation in the mitochondria and during photosynthesis in the chloroplasts of plants. As protons move across the membrane, they create an electrochemical gradient that drives the synthesis of ATP by the ATP synthase enzyme.
