Q: What helps amplify the effects of extracellular signals?


Read this paragraph and choose the correct option from the provided answers:

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.

 Choices:

- electrical cascades

- spontaneous cascades

- mutation cascades

- enzymatic cascades


A:
enzymatic cascades
