Answer:
Cell-surface receptors are involved in most of the signaling in multicellular organisms. There are three general categories of cell-surface receptors: ion channel-linked receptors, G-protein-linked receptors, and enzyme-linked receptors.
Cells contain proteins known as receptors, which bind to signaling molecules and cause a physiological response. Different receptors recognize different molecules.
Receptors are proteins, typically cell surface receptors, that bind to ligands and cause immune system responses.
Cells contain proteins known as receptors, which bind to signaling molecules and cause a physiological response. Different receptors recognize different molecules.
Insulin receptors bind insulin, dopamine receptors bind dopamine, nerve growth factor receptors bind nerve growth factor, and so on.
Thus, due to this, receptors are needed for cell signaling.
