Final answer:
Enzyme/enzyme-linked receptors and G protein-mediated receptors are both involved in cell signaling and have similar roles in transmitting signals into the cell.
Step-by-step explanation:
Enzyme/enzyme-linked receptors and G protein-mediated receptors are both involved in cell signaling and have similar roles in transmitting signals into the cell.
Both types of receptors are cell-surface receptors that bind to specific ligands to initiate a signal cascade.
However, there are some key differences between these two types of receptors. Enzyme-linked receptors have intracellular domains that are associated with an enzyme, while G-protein-linked receptors interact with a nearby membrane protein, such as an ion channel or an enzyme, through an associated G-protein.
