How is the proton concentration gradient created inside and outside of mitochondrial inner membrane?
The proton concentration gradient across the mitochondrial inner membrane is created by the electron transport chain (ETC) during oxidative phosphorylation. As electrons are transferred through the ETC, energy released from these reactions is used to pump protons (H⁺) from the mitochondrial matrix into the intermembrane space, resulting in a higher concentration of protons outside the matrix. This creates a proton motive force, which is essential for ATP synthesis as protons flow back into the matrix through ATP synthase.

What is the energy of hydrogen ion gradient created across the inner mitochondrial membrane used to make?
The hydrogen falls down its electrochemical gradient, from an area of high concentration to an area of lower concentration, through the ATP synthase and provides the force to power this synthase and synthesize ATP.
What is the energy of the hydrogen ion gradient created across the inner mitochondrial membrane used to make?
electron transport chain
What creates a Na concentration gradient in the proximal tubule?
The Na concentration gradient in the proximal tubule is created by Na+/K+-ATPase pumps on the basolateral membrane actively pumping Na+ out of the cell, generating a low intracellular Na+ concentration. This drives passive reabsorption of Na+ from the lumen of the tubule into the cell down its electrochemical gradient.
Why do hyrdogen ions flow back across the mitocondrian membrane?
Hydrogen ions (H⁺) flow back across the mitochondrial membrane primarily due to the electrochemical gradient created by the electron transport chain during cellular respiration. As electrons are transferred through protein complexes, protons are pumped from the mitochondrial matrix into the intermembrane space, generating a higher concentration of H⁺ ions outside the matrix. This gradient creates potential energy, which drives the flow of protons back into the matrix through ATP synthase, facilitating the synthesis of ATP from ADP and inorganic phosphate. This process is essential for efficient energy production in cells.
Most of the ATP of aerobic respiration is produced directly from membrane hydrogen gradients created by?
Most of the ATP of aerobic respiration is produced directly from membrane hydrogen gradients created by the process of oxidative phosphorylation. This involves the transfer of electrons along the electron transport chain in the inner mitochondrial membrane, leading to the pumping of protons across the membrane, creating a gradient that drives ATP synthesis through ATP synthase.

What does ATP synthase use to add phosphate to ADP?
ATP synthase uses the proton gradient created by the electron transport chain to drive the formation of ATP from ADP and inorganic phosphate. This process occurs in the inner mitochondrial membrane in eukaryotic cells and the plasma membrane in prokaryotic cells.
What causes the H ions in the intermembrane space space to move through the channels in the membrane and out 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 process of chemiosmosis is for making molecules of?
The process of chemiosmosis is for making molecules of adenosine triphosphate (ATP), which is the primary energy carrier in cells. It involves the movement of protons across a membrane, usually the inner mitochondrial membrane or the thylakoid membrane in chloroplasts, to generate ATP from ADP and inorganic phosphate. This process relies on the proton gradient created by electron transport chains during cellular respiration or photosynthesis.
What portion of the mitochondria has the lowest pH?
According to another answer to a similar question here on this site, "The intermembrane space has the lowest pH, highest concentration of H+, due to the gradient created by the electron transport chain."
