Solved What is the role of glucose in catabolite repression ... - Chegg
Our expert help has broken down your problem into an easy-to-learn solution you can count on. Question: What is the role of glucose in catabolite repression? It increases the levels of cAMP in the cell, stimulating transcription from the lac operon. It decreases the levels of cAMP in the cell, repressing transcription from the lac operon.
