Question

Which of the following statements is false about cyclic AMP?

1) It has targets in multiple signal transduction pathways
2) The enzyme adenylyl cyclase catalyzes its formation
3) It is produced from ATP
4) It is a second messenger
5) It possesses enzymatic activity

Answer 1

Cyclic AMP, or cAMP, is a second messenger that is produced from ATP by the enzyme adenylyl cyclase. It has targets in multiple signal transduction pathways but does not possess enzymatic activity.

Step-by-step explanation:

The false statement about cyclic AMP is: It possesses enzymatic activity.

Cyclic AMP, or cAMP, is a second messenger that plays a crucial role in cell signaling. It is produced from ATP by the enzyme adenylyl cyclase, and it has targets in multiple signal transduction pathways. However, cAMP itself does not possess enzymatic activity.
