Did you know?
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 … WebJun 16, 2024 · In chloroplast, chemiosmosis occurs in the thylakoid. This membrane system has its own transport chain and ATP synthases. One of the major differences between chemiosmosis in mitochondria and in …
WebNo. Oxidation and reduction reactions occur in tandem in a reaction called a redox reaction. They occur in tandem because electrons can move from one molecule to another: one is losing electrons (oxidation). and the other is gaining electrons (reduction). What is the function of molecules like NAD+/NADH and FAD/FADH2in cells? WebThis flow of hydrogen ions across the membrane, called chemiosmosis, must occur through a channel in the membrane via a membrane-bound enzyme complex called ATP synthase ( Figure 8.15 ). The tendency for movement in this way is much like water accumulated on one side of a dam, moving through the dam when opened.
