In mitochondria, protons (H⁺ ions) re-enter the matrix primarily through ATP synthase, a protein complex located in the inner mitochondrial membrane. This process occurs during oxidative phosphorylation, where the flow of protons down their concentration gradient drives the synthesis of ATP from ADP and inorganic phosphate. Additionally, some protons may re-enter the matrix through other transport mechanisms, such as the uncoupling proteins, but ATP synthase is the key player in ATP production.
What else can I help you with?
What ions accumulate in the outer compartment of the mitochondria during electron transport phosphorylation?
Protons (H+) accumulate in the outer compartment of the mitochondria during electron transport phosphorylation. This forms an electrochemical gradient that drives ATP synthesis as protons flow back into the mitochondrial matrix through ATP synthase.
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
Which factor most likey has the greatest effect on the number molecules mitochondria can produce?
The speed of the H+ ions.
Which type of cell transport is used by mitochondria to generate energy by allowing hydrogen (H ) ions to flow through a membrane protein?
Mitochondria utilize facilitated diffusion to generate energy by allowing hydrogen ions (H⁺) to flow through a membrane protein known as ATP synthase. This process occurs during oxidative phosphorylation, where the flow of H⁺ ions down their concentration gradient drives the synthesis of ATP from ADP and inorganic phosphate. The movement of these ions is aided by the electrochemical gradient established by the electron transport chain.
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 part of the mitochondria stores a high concentration of H plus ions?
The intermembrane space of the mitochondria stores a high concentration of H plus ions. This creates a proton gradient that drives the production of ATP through oxidative phosphorylation.
What causes the h ions in the intermembrane space to move through the channels in the membrane and out the into the matrix?
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.

The speed of the H+ ions.
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.
H ions build up in what space?
as the electrons pass down the electron transport chain, h+ ions build up in the _____ space?
