The chemiosmotic coupling hypothesis of oxidative phosphorylation proposes that Adenosine Triphosphate (ATP) is formed because
Options
- AHigh energy bonds are formed in mitochondrial proteins
- BADP is pumped out of the matrix into the intermembrane space
- CA proton gradient forms across the inner membrane
- DThere is a change in t of the permeability inner mitochondrial membrane toward Adenosine Diphosphate (ADP)
Correct answer
C. A proton gradient forms across the inner membrane
Step-by-step solution
The production of ATP with the help of energy liberated during oxidation of reduced coenzymes and terminal oxidation is called oxidative phosphorylation. Peter Mitchell (1961) put forward a hypothesis known as chemiosmotic hypothesis for ATP synthesis. According to this when electrons flow from duel proton, electron carrier to a non-hydrogen carrier the H + are released and expelled into the intermembrane space and thus creates a proton gradient with higher concentration of H + in the inter membranous space than th
