Hormones often cause a cell to elicit multiple responses; this is because ________.
A) there are thousands of receptors on the cell membrane
B) the receptors bind to several hormones at the same time
C) the protein kinases are rapidly metabolized into functional amino acids
D) during protein kinase activation, enzymes phosphorylate many other enzymes

Question

Quizplus · Accepted Answer

Hormones often activate protein kinases, which in turn activate many other enzymes through phosphorylation. This cascade of enzyme activation can lead to multiple responses in the cell. Choices A and B are incorrect because the number of receptors or hormones bound does not necessarily determine the number of responses, and choice C is not relevant to hormone signaling.
