(a)
Interpretation:
Niacin is needed or not for the proper functioning of the ETC has to be determined.
Concept introduction:
Electron transport chain is a sequence of biochemical reactions in which electrons and hydrogen atoms from the citric acid cycle are transferred to various intermediate carriers and finally reacts with molecular oxygen to form a water molecule. There are four complexes associated with the electron transport chain that is present in the inner mitochondrial membrane. The four complexes that help in the electron transfer in the electron transport chain are:
Complex I: NADH-coenzyme Q reductase.
Complex II: Succinate-coenzyme Q reductase.
Complex III: Coenzyme Q-cytochrome c reductase.
Complex IV: Cytochrome c oxidase.
An overview of the electron transport chain is as follows:
The B-vitamins consist of a group of vitamins that are water soluble and acts as precursors for enzyme cofactors.
