|
Glycolysis operates as long as it is supplied with NAD that can pick up hydrogen atoms
|
|
|
Glycolysis occurs in cytosol
|
|
|
Enzymes of TCA cycle are present in mitochondrial matrix
|
|
|
Oxidative phosphorylation takes place in outer mitochondrial membrane
|
Detailed explanation-1: -Final answer: Oxidative phosphorylation that occurs in the outer mitochondrial matrix is the incorrect statement.
Detailed explanation-2: -Explanation of the correct answer: Oxidative phosphorylation is the process of ATP synthesis by the movement of electrons. It is the final step in cellular respiration. It occurs in the inner mitochondrial membrane.
Detailed explanation-3: -During oxidative phosphorylation, electrons derived from NADH and FADH2 combine with O2, and the energy released from these oxidation/ reduction reactions is used to drive the synthesis of ATP from ADP.
Detailed explanation-4: -Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
Detailed explanation-5: -Glycolysis operates as long as it is supplied with NAD that can pick up hydrogen atoms that are released during oxidation of PGAL. Enzymes of TCA cycle are present in the mitochondrial matrix space. Oxidative phosphorylation takes place in the inner mitochondrial membrane. Thus, the correct answer is option C.
