What happens to K⁺ transport by valinomycin when the membrane is cooled below its transition temperature?

#Unit 2. Cellular Organization

K⁺ transport ceases because the ionophore-K+ complex cannot diffuse through the membrane when the lipids are immobilized in a sol-like state
K⁺ transport increases because the ionophore-K+ complex can diffuse through the membrane when the lipids are immobilized in a gel-like state.
K⁺ transport ceases because the ionophore-K⁺ complex can diffuse through the membrane when the lipids are immobilized in a gel-like state.
