Explanation:
Detailed explanation-1: -Second messengers are molecules that relay signals received at receptors on the cell surface-such as the arrival of protein hormones, growth factors, etc.-to target molecules in the cytosol and/or nucleus.
Detailed explanation-2: -Many second messenger molecules are small and therefore diffuse rapidly through the cytoplasm, enabling information to move quickly throughout the cell.
Detailed explanation-3: -Cyclic AMP (cAMP) Another second messenger used in many different cell types is cyclic adenosine monophosphate (cyclic AMP or cAMP), a small molecule made from ATP.
