Question

The Mitchell or charismatic hypothesis predicts the __________________________.

• A. Existence of a higher pH in the endoplasmic reticulum than in the cytosol
• B. Symmetrical distribution of ATPase of the inner membrane of the mitochondria
• C. Synthesis of ATP as protons flow along a gradient across inner mitochondrial membrane
• D. Absence of ATPase in the inner mitochondrial membrane

Answer 1

The correct option is C Synthesis of ATP as protons flow along a gradient across inner mitochondrial membrane

The chemiosmotic hypothesis was proposed by Peter Mitchell. This hypothesis stated that a proton-motive force was responsible for driving the synthesis of ATP. In this hypothesis, protons would be pumped across the inner mitochondrial membrane as electrons went through the electron transfer chain.

So the correct answer is option C.
