94. K+ channels in the heart do not have binding sites for ACh, yet parasympathetic release of
ACh causes outward flux of K+ from heart cells. How does this occur?
95. What would happen if the G-protein coupled receptor in heart cells that binds to ACh had
a mutation that caused it to bind more tightly to the G-protein alpha subunit?
