Chemiosmosis in chloroplasts that results in the donation of a proton for the production of adenosine triphosphate (ATP) in plants.
A central feature is the formation of a hydrogen ion (proton) concentration gradient and an electrical charge across intact lamellae. You can also find Chemiosmotic Hypothesis, ATP synthesis NEET Video | EduRev ppt and other NEET slides as well.
This process, known as chemiosmotic coupling of oxidative phosphorylation, powers nearly all cellular activities, including those that generate muscle movement and fuel brain functions. You can see some Chemiosmotic Hypothesis NEET Notes | EduRev sample … Chemiosmotic hypothesis: Proposed by Peter Mitchel (1970) to explain how NADH oxidation is coupled to ATP synthesis. CHEMIOSMOTIC HYPOTHESIS Proposed by Peter Mitchell 1961 and further elaborated 1966 Competing hypotheses 1) Chemical hypothesis (i.e. The general features are now widely accepted. S �iJ�� As electrons are passed down the chain, protons are pumped across the membrane (between the inner membrane and outer membrane of the cristae or thylakoids).

The chemiosmotic hypothesis is based on four postulates, which we paraphrase from Mitchell [1]: i. electron transfer chains translocate H+; ii.
