Hormone X activates the cAMP second messenger system in its target cells. The greatest response by a target cell would come from
________. A. applying a molecule of hormone X to the extracellular fluid surrounding the cell B. injecting a molecule of hormone X into the cytoplasm of the cell C. applying a molecule of cAMP to the extracellular fluid surrounding the cell D. injecting a molecule of activated, cAMP-dependent protein kinase into the cytoplasm of the cell
Hormone X activates the cAMP second messenger system in its target cells. The greatest response by a target cell would come from applying a molecule of cAMP to the extracellular fluid surrounding the cell.
<h3>What is cAMP?</h3>
This is an intracellular second messenger molecule, which regulates activity of hormonal action.
the cAMP stands for cyclic adenosine monophosphate.
<h3>What is a second messenger molecule?</h3>
The molecules that transfer the signal received from the cell surface to the target hormone are called the second messenger molecules.
