1.	If rotenone is added to the mitochondrial electron transport chain then ____________(a) Succinate oxidation remains normal(b) P: O ratio of NADH is reduced from 3:1 to 2:1(c) Oxidative phosphorylation is uncoupled at site I(d) Rate of NADH oxidation is diminished to two-thirds of its initial valueI got this question in quiz.My question is based upon ATP Synthesis-1 topic in section Oxidative Phosphorylation and Photophosphorylation of Biochemistry
Answer» CORRECT choice is (a) Succinate oxidation remains normal To EXPLAIN I would say: If ROTENONE is added to the mitochondrial electron transport chain succinate oxidation remains normal.
