Cyclic AMP is Synthesized from ATP by an Enzyme Called

Question

Cyclic AMP is synthesized from ATP by an enzyme called ________ which is involved in ________.
A) adenylate cyclase / catabolite repression
B) adenylate cyclase / transcriptional activation
C) cAMP receptor protein (CRP) synthase / catabolite repression
D) cAMP receptor protein (CRP) synthase / transcriptional activation

Accepted Answer

Adenylate cyclase synthesizes cyclic AMP (cAMP) from ATP, and it is involved in catabolite repression, a regulatory mechanism in bacteria where the presence of a preferred carbon source (like glucose) inhibits the use of other carbon sources.
