Homework Answers
any cell that has receptor for a specific chemical signal is called a target cell.
during cell signalling the cell which produces the signal is called signaling cell while the cell which respond to the signal is called target cell.

Question (1 point) 1st attempt Which statement is true about cell-surface receptors? Choose one: O All extracellular signal molecules bind to a single type of receptor. O All cell-surface receptors bind to a single, unique extracellular signal molecule. O Each cell-surface receptor can bind to an endless variety of extracellular signal molecules. Some cell-surface receptors can bind to multiple signal molecules. O All drugs block the activation of ion-channel-coupled receptors. 11 OF 15 QUESTIONS COMPLETED 07/15 >
