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

#Unit 2. Cellular Organization
  1. K+ transport ceases because the ionophore-K+ complex cannot diffuse through the membrane when the lipids are immobilized in a sol-like state

  2. K+ transport increases because the ionophore-K+ complex can diffuse through the membrane when the lipids are immobilized in a gel-like state.

  3. K+ transport ceases because the ionophore-K+ complex can diffuse through the membrane when the lipids are immobilized in a gel-like state.

  4. K+ transport ceases because the ionophore-Kcomplex cannot diffuse through the membrane when the lipids are immobilized in a gel-like state.
