Identify a secondary signaling pathway that controls the proliferation of B cells.
A) deactivation by tyrosine kinase
B) activation by phosphatase
C) both of these
D) neither of these

Question

Quizplus · Accepted Answer

The question asks for a secondary signaling pathway that controls the proliferation of B cells, which implies there is already a primary signaling pathway in place. However, the answer choices given suggest the secondary pathway involves either deactivation by tyrosine kinase or activation by phosphatase, which do not make sense in this context. Therefore, the best answer is D - neither of these - as there is no known secondary signaling pathway that specifically controls B cell proliferation.
