Question

The primary messenger molecules bind to the transmembrane receptors.

(a) True

(b) False

This question was addressed to me in a job interview.

Enquiry is from Cell Signaling Systems topic in section Cell Signaling and Signal Transduction of Cell Biology

Answer 1

Correct choice is (a) True

For explanation I would say: The primary messenger molecules bind to the transmembrane receptors to initiate intracellular responses such as transcription, translation, cell death (apoptosis). The second messenger molecules are then generated intracellularly to further the elicited response.
