Question

A pathway is given below showing the synthesis of Compound V from precursors I, II, III, and IV via the action of enzymes 1, 2, 3, and 4 (the same pathway as in question 1). You grow a mutant on several different minimal media preparations, and find that it can only grow on media that is supplemented with compounds IV or V. What compound will accumulate in this mutant?A. Compound IB. Compound IIC. Compound IIID. Compound IVE. Compound

Answer 1

C. Compound III

Explanation:

A metabolic pathway can be defined as a series of linked (successive) chemical reactions that are produced within the cell. In an enzymatic reaction, the reactants, intermediates, and products are referred to as 'metabolites'. These enzymatic products generally act as substrates for the successive chemical reactions. The metabolic pathways can be classified into anabolic (require energy to synthesize molecules) and catabolic (release energy) pathways.
