The correct answer is: Protons are pumped out of the mitochondrial matrix into the intermembrane space
Chemiosmosis can be described as movement of ions across a selectively permeable membrane, down their electrochemical gradient. It occurs during the cellular respiration within mitochondria and it is involved in ATP synthesis (oxidative phosphorylation via ATP synthase).
Electrons from electron carriers (NADH and FADH) donate electrons to the electron transport chain and that causes changes in protein complexes of electron transport chain. As a consequence, protein complexes pump H+ across a selectively permeable cell membrane from the mitochondrial matrix into the intermembrane space of mitochondria.
H+ can only get back and pass through the inner mitochondrial membrane with the help of ATP synthase (down their electrochemical gradient). ATP synthase turned by the force of the H+ diffusing through it forms ATP by adding a phosphate to ADP.
Mangrove forests were traditionally viewed as A. unproductive wastelands. People therefore reasoned that their removal would improve the health of their ecosystems, leading to their degradation.
Prophase. This is the first stage of nuclear division

Answer: facilitate the transport of substances across a cell membrane.
Explanation:
The organelles in a cell will be much smaller than the organs in your body. Cells are the smallest functioning unit in a body, which work together to create tissue, which then creates organs, which then creates organ systems, which then leads to a healthy body. Just as a cell has different organelles for different functions, so will a body have different organs for different functions.
