Question

Use the References to acess important values if needed for this question. Suppose a sequence of enzymatically catalyzed reactions converts substrate A to final product D through a sequence of reactions involving the production of intermediate products B and C as shown. Product D inhibits enzyme E If the enzymes E1-E3 are all present in a test tube and substrate A is added to the reaction mixture, how will the concentration of product D change? E E2 E increase to a fixed value first increase, then decrease remain at zero oscillate between zero and the concentration of A added increase to the concentration of A added Submit Answer Try Another Version 1 item attempt remaining

Explanation / Answer

Increase to a fix value.

The option you have selected would be correct if both A and D were present intially. But, here, only enzymes are present. So when we add A, the production of D starts. Yes, the rate of increase of D may first increase then decrease. But, the concentration of D increases and attains a fixed value at equilibrium.
