WebMay 20, 2024 · Hydrogen ions in the matrix space can only pass through the inner mitochondrial membrane through a membrane protein called ATP synthase. As protons move through ATP synthase, ADP is turned into ATP. The production of ATP using the process of chemiosmosis in mitochondria is called oxidative phosphorylation. WebThe influx of H+ ions also generates a membrane potential of about 20 mV, wherein the inside of the vesicle is positive relative to the cytoplasm around the vesicle. In the second step, an H+/Ach antiporter moves one molecule of Ach into the vesicle in exchange for moving two H+ ions back into the cytoplasm."

WebChemiosmosis, in simple terms, is the movement of protons (hydrogen ions, or H+) from the mitochondrial matrix to the intermembrane space across the inner membrane of the mitochondria (in most eukaryotes). In plants, chemiosmosis occurs in the chloroplast, while in prokaryotes, this process takes place in the cell membrane. WebAns : Energy released during electron transport is used to move H+ into the Intermembrane space .

WebApr 9, 2024 · If the membrane were open to diffusion by the hydrogen ions, the ions would tend to diffuse back across into the matrix, driven by their electrochemical gradient. Recall that many ions cannot diffuse through the nonpolar regions of phospholipid membranes without the aid of ion channels. WebTransmembrane ATPases often use ATP hydrolysis to pump ions against their concentration gradients. ATP synthase is like one of these acting in reverse, where H+ ions flow down an electrochemical (concentration and …
