    Option (d).

    Explanation:

    Dehydrogenase may be defined as the enzyme that belongs to the group of oxidoreductase. This enzyme uses FAD, FMN as a co enzyme to carry out the reactions.

    The main function of the dehydrogenase enzyme is to oxidize the substrate. The oxidation occur by the removal of hydrogen molecule or the transfer of the hydrogen to the by reducing the electron acceptor. They can cause the reversible reactions as well.

    Thus, the correct answer is option (d).

    Answer: d. oxidizes a substrate by removing a hydrogen molecule.

    Explanation:

    The dehydrogenase is the enzyme which is responsible for oxidizing the substrate by removing the hydrogen molecule and transfers the hydrogen molecule to the proton acceptor that can be either the NAD/NADP or a flavin enzyme. This enzyme is used in the cytochrome system during the process of respiration that is required for the net production of the ATP molecules.
