Final answer:
Once intercellular signals reach inside a cell through receptors, they are transferred to the cytoplasm in a process known as signal transduction, which can trigger various cellular responses.
Step-by-step explanation:
Once intercellular signals reach the inside of a cell using some type of receptor, what typically happens is that the signal is transferred to the cytoplasm. This continuation of a signal within the cell is known as signal transduction. Cell-surface receptors undergo a change when a ligand binds to them, resulting in the transmission of the signal through the membrane and into the cell's cytoplasm. Signal transduction can lead to a variety of cellular responses such as the activation of enzymes, changes in the function of ion channels, alterations in gene expression, and other regulatory events within the cell.
