In the process leading from a signaling molecule to a cellular response, relay proteins are involved in
A) signal transduction
B) recognition of the messenger
C) receptor activation
D) cellular response

Question

Quizplus · Accepted Answer

Relay proteins are involved in signal transduction, which is the process of converting an extracellular signal (signaling molecule) into an intracellular response. This involves a series of relay proteins that transmit the signal downstream to ultimately cause a cellular response. Relay proteins are not directly involved in the recognition of the messenger or receptor activation, but they do play a crucial role in transducing the signal from the receptor to downstream effectors. Therefore, choice A is the best answer.
