A) high energy bonds are formed in mitochondrial proteins
B) ADP is pumped out of the matrix into the Inter membrane space
C) a proton gradient forms across the inner membrane
D) there is a change in the permeability of the inner mitochondrial membrane toward Adenosine Diphosphate (ADP)
Correct Answer: C
Solution :
| [C] The production of ATP with the help of energy liberated during oxidation of reduced coenzymes and terminal oxidation is called oxidadve 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 inter membrane space and thus, creates a proton gradient with higher concentration of \[{{H}^{+}}\]in the inter membranous space than the matrix. Due to proton motive force the protons flow back and energy liberated during this back flow of protons activate AT Pase present in \[{{F}_{1}}\]head to synthesize ATP. |
