In this hypothesis, protons would be pumped across the inner mitochondrial membrane as electrons went through the electron transfer chain
Chemiosmosis involves the pumping of protons through special channels in the membranes of mitochondria from the inner to the outer compartment
Chemiosmosis in Photosynthesis or chloroplast simple steps
In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient
For instance, hydrogen ions (H+) move across a membrane during photosynthesis or in cellular respiration to form adenosine triphosphate (ATP)
(just like turbine in hydroelectric power plant where water forces turbine movement, here flow of H+ ions drives ATP synthesis) The proton gradient (Proton motive force) driven ATP synthesis is called Chemiosmosis
The uneven distribution of H + ions across the membrane establishes both concentration and electrical gradients (thus, an electrochemical gradient), owing to the hydrogen ions’ positive charge and
The energy released from electron flow is used to pump protons (H+) from
In each of these situations, chemiosmosis is the process that allows the cell to harvest energy from oxidation reactions and synthesize ATP
The turning of this molecular machine harnesses the potential energy stored in the hydrogen ion gradient to add a phosphate to ADP, forming ATP
Chemiosmosis is a special type of diffusion that happens over the plasma membrane
It is also the method used in the light reactions of photosynthesis to harness the energy of sunlight in the process of photophosphorylation
Provide your answer below: Mar 19, 2021 · Chemiosmosis is used to generate 90 percent of the ATP made during aerobic glucose catabolism
Nov 27, 2019 · Chemiosmosis is that the movement of ions across a tissue layer, down their electrochemical gradient
