Question
The chemiosmotic coupling hypothesis of oxidative phosphorylation proposes that Adenosine Triphosphate (ATP) is formed because
Options
A.high energy energy bonds are formed in mitochondrial proteins
B.ADP is pumped out of the matrix into the intermembrane space
C.a protoe is a change in the permeability of the inner mitochondrial membrane
D.there is a change in the permeability of the inner mitochondrial membrane toward Adenosine Diphosphate (ADP)
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 frhypothesis for ATP synthesis, According to this when electrons flow from dual proton, electron carrier to a non-hydrogen carrier the H+ are released and expalled into the intermembrane space and thus creates a proton gradilent 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 ATP ace present in F1 fead to synthesixe ATP.
