Q: Answer the following question given this paragraph: The effects of extracellular signals can also be amplified by enzymatic cascades. At the initiation of the signal, a single ligand binds to a single receptor. However, activation of a receptor-linked enzyme can activate many copies of a component of the signaling cascade, which amplifies the signal. Q: What helps amplify the effects of extracellular signals? Choices: - electrical cascades - spontaneous cascades - mutation cascades - enzymatic cascades A:
A: enzymatic cascades
