Question

Which of the following properly lists the order of events in cell signaling?

a. signal and response
b. reception, transduction/amplification, and response
c. perception and amplification
d. signal, amplification, and response

Answer 1

B

Step-by-step explanation:

Cell signaling can be divided into 3 stages.
Reception: A cell detects a signaling molecule from the outside of the cell. Transduction/Amplification: When a signaling molecule connects to a receptor, it alters the receptor protein in some way, triggering the transduction process. Each relay molecule in the signal transduction pathway affects the following molecule in the pathway.
Response: The signal triggers a specific cellular response.
