Answer:
option B) intracellular receptors are present only in target cells.
Explanation:
The cell membrane or plasma membrane is composed of phospholipids and thus hydrophobic in nature, this allows the lipid soluble signaling molecules to cross the membrane. The cell membrane of all cells consist of phospholipids thus hydrophobicity of each cell membrane allows lipid soluble signaling molecules to pass through the plasma membrane. The testosterone cross the membranes of all cells but affect only target cells because of intracellular recepters that are located in target cell. The binding of signaling molecules to recepter generates a response. Thus, option B is correct.
The lipid molecule signaling is responded to by the target cell only due to the presence of intracellular receptors.
What is lipid signaling?
Lipid signaling is defined as the transfer of the response to the target cell with lipids as the source molecules. The lipids act as the messenger across the cell membrane and enable the cell response.
The lipid molecules are the messenger molecules and cross the phospholipid bilayer cell membrane. The molecules are able to bind to the receptors on the target cell.
The other cell acts as the receptors for the lipid messengers, and thereby avoid the signal and the response from the target cell is achieved.
Thus, the lipid-soluble signaling is achieved with the target cells only as there has been the presence of receptors to the target cell only. Thus, option B is correct.
