Explanation / Answer
Question number 22 :
Answer : The correct option is C (ATP synthase enzyme complex)
Explanation : ATP synthases which are present in the inner mitochondrial memebrane are central to ATP production in mitochondria during oxidative phosphorylation and in chloroplasts during photophosphorylation. The proton gradient needed to drive ATP synthesis is produced by other types of proton pumps powered by substrate oxidation.
Question number 23 : The correct answer is B (O2)
Explanation : In the final step of the respiratory chain, Complex IV, also called cytochrome oxidase, carries electrons from cytochrome c to molecular oxygen, reducing it to H2O. so it is a reactant/final electron acceptor in the aerobic respiration.
