Which factor most likely has the greatest effect on number of molecules mitochondria can produce?

The amount of energy the flow H+ ions have EDIT: The speed of the H+ ions


What part of the mitochondria stores a high concentration of H plus ions?

The intermembrane space.

What drives the ATP synthase reactions that produced ATP?

The proton gradient produced by the electron transport chain powers ATP production. This process is called chemiosmosis, in which H+ ions from the thylakoid space (in mitochondria they are in the intermembrane space) pass through ATP synthase to areas of lower concentration (in chloroplasts, the stroma, and in mitochondria, the mitochondrial matrix). As they pass through ATP synthase, the catalytic knob of the ATP synthase is turned. The turning of this knob (which is powered by diffusion of H+ ions) powers the anabolic production of ATP.


The energy from the electrons moving down the chain is used to move H ions across the?

Energy from the electrons move down the chain is used to move H plus ions across the inner membrane. H plus ions move through channels of ATP synthase in the inner membrane.


Where is ATP made in the mitochondria?

Across the inner membrane. As H+ ions are pumped through ATP synthase, ADP + Pi --> ATP


How is gradient of ions maintained in the mitochondria?

By the action of electrons going down the electron transfer chain the energy is provided to pump H + into the outer lumen of the mitochondria creating the concentration gradient for H + to come down it's concentration gradient through the ATP synthase.


What causes the H ions in the intermembrane space to move through the channels in the membrane and out into the matrixs?

The energy of the high energy molecules used for every time 2 high energy electrons move down the chain causes the H+ ions to move to the matrix.
