Which of the following are potential roles of NADPH in the cell: A. Reduction of cytochrome P450 enzymes B. Synthesis of cholesterol C. Synthesis of aspartate D. Oxidation of hydrogen peroxide

The enzyme glutathione reductase catalyzes the conversion of the molecule GSSG to GSH, which is essential in order for cells to counteract the effects of reactive oxygen species in the cytoplasm. Glutathione reductase cleaves a single disulfide bond within the GSSG molecule, resulting in two GSH molecules. Solely using this given information, how does the oxidation number change from a single GSSG molecule to a single GSH molecule? A.+2 to 0B.+1 to 0C.0 to -1D.0 to -2
