question 10 of 10
in a hydrogen ion pump, the energy is used to join small molecules together to make larger ones. which factor most likely has the greatest effect on the number of molecules mitochondria can produce?
a. the shape of the protein channel
b. the amount of energy the flowing h+ ions have
c. the size of the cell nucleus
d. the size of the membrane proteins

Explanation:

In a hydrogen - ion pump, the energy from the flow of H+ ions (proton - motive force) is used to drive endergonic reactions like joining small molecules together. The energy amount of these flowing H+ ions is crucial for such processes. The shape of the protein channel is related to ion passage but not the main energy - providing factor. The size of the cell nucleus is not related to this energy - using process in the hydrogen - ion pump, and while the shape of membrane proteins is important for structure and function, the key here is the energy from the H+ ions.

Answer:

B. The amount of energy the flowing H+ ions have
