Chemiosmosis is the movement of ions across a semipermeable membrane through an integral membrane protein, down their electrochemical gradient. An important example is the formation …

Jul 23, 2025 · The chemiosmotic hypothesis is a theory that explains how cells produce energy. It suggests that energy is generated through the movement of ions across a membrane, creating …

Aug 2, 2025 · The formulation of the chemiosmotic theory by Peter Mitchell in 1961 marked a significant advancement in our understanding of cellular energy. His hypothesis, initially met …

: relating to or being a hypothesis that seeks to explain the mechanism of ATP formation in oxidative phosphorylation by mitochondria and chloroplasts without recourse to the formation …

Feb 3, 2023 · Peter D. Mitchell first proposed the chemiosmotic theory in 1961. His theory suggests chemiosmosis is driven by an electrochemical proton gradient across the inner …

Mar 5, 2024 · The chemiosmotic theory describes how energy is used to create a proton gradient across a membrane. The gradient is used to produce ATP, the energy currency of the cell.

This process, known as chemiosmotic coupling of oxidative phosphorylation, powers nearly all cellular activities, including those that generate muscle movement and fuel brain functions.

This page discusses the chemiosmotic theory of ATP synthesis in chloroplasts, supported by observations that light illumination increases the alkalinity of the surrounding medium due to …

The chemiosmotic theory clearly explains the dependence of electron transfer on ATP synthesis. It is the return flow of protons through the ATP synthase that powers ATP synthesis and …

Oct 28, 2025 · The Chemiosmotic Hypothesis, proposed by Peter Mitchell in 1961, explains how ATP is synthesized in both mitochondria and chloroplasts through the movement of protons …
