You are studying a cell that contains ACh-activated GIRK channels. Which of the following dimers would increase the ability of the cell to fire action potentials in the presence of ACh, and why? a. β-γ dimer, becasue this dimer decreases the amount of open GIRK channels in the cell and therefore reduces their hyperpolarizing effect on the cell, increasing its ability to fire an action potential. b. α-GDP dimer, because this dimer would bind to the β-γ dimer leading to...
