If the diagram below represents a catabolic pathway, and enzyme 1 requires NAD⁺, what type of reaction does enzyme 1 catalyze? A)reduction B)oxidation C)isomerization D)any of the above E)none of the above

Question

Enzyme 1 requires NAD⁺, which suggests that it catalyzes an oxidation reaction. This is because NAD^and are likely electron donors, and enzyme 1 would require these substrates to transfer electrons to an acceptor molecule during an oxidation reaction. Neither isomerization nor reduction necessarily involves the transfer of electrons, so these options are less likely.
