As shown in the image, a series of enzymes catalyze the conversion of Molecule A to Molecule C. Molecule C functions as a co-repressor for the operon controlling production of Enzyme A.
Which of the following scenarios would most likely result from the introduction of a large amount of Molecule C?

Concentration of Enzyme A will decrease.

Solution

The correct option is A Concentration of Enzyme A will decrease.
Molecule C is a co-repressor of the operon and controls the production of enzyme A, when molecule C is released in large quantities it will repress the production of enzyme A thus decreasing its concentration.
So, the correct answer is 'Concentration of Enzyme A will decrease'
