Question

Match the following \[ \begin{array}{|c|l|c|l|} \hline & List-I & & List-II \hline A & \text{Carbon source} & I & \text{Enzyme cofactor} B & \text{Nitrogen source} & II & \text{Energy and cell material} C & \text{Trace elements} & III & \text{Protein and nucleic acid synthesis} D & \text{Buffer} & IV & \text{pH maintenance} \hline \end{array} \] The correct matching is

• A. A -- II, B -- III, C -- I, D -- IV
• B. A -- III, B -- II, C -- IV, D -- I
• C. A -- IV, B -- I, C -- II, D -- III
• D. A -- I, B -- IV, C -- III, D -- II

Hint:

Functions of culture medium components: \[ \boxed{ \begin{aligned} \text{Carbon} &\rightarrow \text{Energy source} \text{Nitrogen} &\rightarrow \text{Proteins and nucleic acids} \text{Trace elements} &\rightarrow \text{Enzyme cofactors} \text{Buffer} &\rightarrow \text{Maintains pH} \end{aligned} } \]
