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

Respuesta :

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.

What is cAMP?

This is an intracellular second messenger molecule, which regulates activity of hormonal action.

the cAMP stands for cyclic adenosine monophosphate.

What is a second messenger molecule?

The molecules that transfer the signal received from the cell surface to the target hormone are called the second messenger molecules.
