WebThe four basic postulates of chemiosmosis are (1) that the membrane-located adenosine triphosphatase (ATPase) reversibly couples the translocation of protons across the membrane to the flow of anhydro-bond equivalents between water and the couple adenosine triphosphate (ATP)/ (adenosine diphosphatase (ADP) + Pi); (2) that the … quod oxford terraceWebChemiosmosis is made possible by the intermembrane space. Having a double membrane area allows for there to be a build up of hydrogen ions, causing a concentration gradient. Then they give up their energy to make ATP as they … quoddy head sp

"Chemiosmosis is the movement of ions across a semipermeable membrane bound structure, down their electrochemical gradient. An important example is the formation of adenosine triphosphate (ATP) by the movement of hydrogen ions (H ) across a membrane during cellular respiration or photosynthesis. Hydrogen ions, or protons, will diffuse from a region of high proton concentratio… " - Chemiosmosis occurs when
