Glucose's Impact on Lac Operon

15. Central Dogma & Gene Regulation / Glucose's Impact on Lac Operon / Problem 2

In the presence of high glucose levels, how does the activity of adenylate cyclase affect cAMP levels and the activity of the lac operon?

A

It increases cAMP levels, activating the lac operon.

B

It decreases cAMP levels, leading to reduced activity of the lac operon.

C

It directly activates the lac repressor, turning off the lac operon.

D

It enhances the binding of RNA polymerase to unrelated promoters.
