Signal amplification relies on:
A)increasing amounts of ligand as signal transduction proceeds.
B)a sequential increase in the different components of the signal transduction pathway.
C)increasing numbers of cell-surface receptors as the signal is transduced.
D)increased activity of protein phosphatases.

Signal amplification is the process by which a small amount of signal is converted into a larger response within the cell. This is achieved through a sequential increase in the different components of the signal transduction pathway. As the signal is transduced from the receptor to the effector, each step amplifies the signal, resulting in a larger response at the end. Therefore, choice B is the correct answer. The other options either do not relate to signal amplification or are incorrect.
