Question

Quizplus · Accepted Answer

A signal transduction pathway is a series of molecular events that occur within a cell in response to a signal from the environment. Similarly, when someone rings the doorbell, it triggers a series of events that lead to a person answering the door. Both involve a signal, a series of steps, and an eventual response or outcome.

Option B, C, and D are not analogous to a signal transduction pathway as they do not involve a signal that sets off a series of molecular events within a cell.
