B)decreasing the number of their transmembrane receptors by endocytosis.
C)uncoupling their receptors from the second message generator.
D)increasing the number of their transmembrane receptors by endocytosis.

Quizplus · Accepted Answer

Cells can increase their responsiveness to an external chemical regulator by increasing the number of their transmembrane receptors, which can be achieved through processes such as exocytosis, allowing more receptors to be present on the cell surface to bind the external molecules.
