Multiple Choice

Which statement about cyclic AMP (cAMP) is false?

cAMP is a secondary messenger involved in signal transduction.

cAMP levels are regulated by phosphodiesterase enzymes.

cAMP is synthesized from ATP by the enzyme adenylate cyclase.

cAMP directly acts as a proton donor in acid-base reactions.

Verified step by step guidance

Understand the role of cyclic AMP (cAMP) in cellular processes. cAMP is known as a secondary messenger, which means it helps transmit signals from the cell surface to the inside of the cell, often involved in signal transduction pathways.

Recognize the synthesis of cAMP. It is synthesized from ATP by the enzyme adenylate cyclase. This conversion is a crucial step in the signaling pathway, allowing cAMP to perform its function as a messenger.

Learn about the regulation of cAMP levels. Phosphodiesterase enzymes play a key role in regulating cAMP levels by breaking it down into AMP, thus controlling the duration and intensity of the signal.

Consider the chemical properties of cAMP. It is important to note that cAMP does not directly act as a proton donor in acid-base reactions. This is a false statement because cAMP's primary role is in signaling, not in participating directly in acid-base chemistry.

Evaluate the statements given in the problem. By understanding the roles and properties of cAMP, identify the false statement: 'cAMP directly acts as a proton donor in acid-base reactions.' This statement is incorrect based on the known functions and characteristics of cAMP.
