WebBinding of a ligand to a receptor changes its shape or activity, allowing it to transmit a signal or directly produce a change inside of the cell In this section, we’ll look at different types of receptors and ligands, seeing how they interact to turn information from outside the cell into a change inside the cell. Types of receptors Web6 Nov 2024 · Answer. First messengers are extracellular signaling molecules such as hormones or neurotransmitters that bind to cell-surface receptors and activate intracellular signaling pathways. Since these molecules cannot physically cross the cell membrane, they rely on second messengers to propagate and amplify the signal within the cell.
