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 the permeability of the 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 dual 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 t
