Question

Choose the correct combination \begin{table}[h!] \centering \begin{tabular}{|c|c|c|} \hline Substrates & End products & Enzyme class
\hline I. Argenosuccinic acid & Arginine + Fumaric acid & 3
\hline II. Fructose 1,6 bisphosphate & Fructose 6 phosphate + iP & 5
\hline III. Glutamic acid + NH$_3$ + ATP & Glutamine + ADP + iP & 6
\hline IV. Malate + NAD$^+$ & Oxaloacetate + NADH + H$^+$ & 1
\hline \end{tabular} \end{table}

• A.
• B.
• C.
• D.

Hint:

In biochemical reactions, enzyme classes and substrate-product relationships are key to identifying the correct combinations. Always check the enzyme class alongside the substrates and products.

Answer 1

The Correct Option is B

From the table provided: \begin{itemize} \item The combination for III is Glutamic acid + NH$_3$ + ATP forming Glutamine + ADP + iP (Enzyme class 6). \item The combination for IV is Malate + NAD$^+$ forming Oxaloacetate + NADH + H$^+$ (Enzyme class 1). \end{itemize} These match the correct enzyme classes, confirming that the correct answer is III and IV.
