PC1 and PC2 form a complex in which PC2 serves as a(n)____________. A)sensor for fluid flow in the kidney tubules B)associated Ca²⁺ ion channel C)water channel D)associated Ca²⁺ ion pump E)associated K⁺ channel

Question

Quizplus · Accepted Answer

The term "associated" suggests that PC2 is not functioning as the ion channel itself, but rather is somehow involved with or required for the function of the Ca²⁺ ion channel. Choice A is incorrect because PC2 is not specifically known to be involved in sensing fluid flow in kidney tubules. Choice C is incorrect because PC2 is not a water channel. Choices D and E are incorrect because PC2 is not an ion pump or ion channel on its own.
