A. I, II
B. I, IV
C. II, III
D. III, IV

Answer 1

Hint: The terminal complex of electron chain transport is Cytochrome c oxidase. Often called complex IV, cytochrome c oxidase is also identified. It is a large complex of transmembrane proteins: The terminal complex of electron chain transport is Cytochrome c oxidase. Often called complex IV, cytochrome c oxidase is also identified. It is a large complex of transmembrane proteins. The chemical reaction in which water is broken down into oxygen and hydrogen is water division.

Complete answer:
The vitamin that is part of the chemical structure of the NAD and NADP coenzymes is nicotinic acid or niacin. In energy production, the NAD/NADP-dependent enzymes are involved in oxidation-reduction reactions. NAD acts as a coenzyme that is necessary for malate oxidation, which occurs in the mitochondrial matrix.
Water photolysis takes place in the thylakoid's lumen. In order to satisfy the gap produced in the photosystem, photolysis or splitting of water takes place. For the water-splitting response of photosynthesis through which oxygen is created, chloride ions are needed.
Conjugate enzymes (e.g. dehydrogenase enzymes) are bound to the protein component of an external non-protein cofactor. Organic or inorganic can be cofactor. A loosely attached organic cofactor is referred to as coenzymes such as NAD, FAD, etc., whereas one is strongly attached, such as heme, biotin, etc. The protein portion of the conjugate enzyme is known as the apoenzyme, while the holoenzyme is known as the entire enzyme.
The terminal complex of electron chain transport is Cytochrome c oxidase. Often called complex IV, cytochrome c oxidase is also identified. It is a large complex of transmembrane proteins.
So, choice B-I, IV is the correct answer.

Note: The energy needed by electrolysis to break water into hydrogen and oxygen is around 260 kJ per mole of water. It will take at least 16 MJ to break one litre of water, which is a massive cost on an industrial scale.
