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-K+ complex cannot diffuse through the membrane when the lipids are immobilized in a gel-like state.

Given below are two statements one is labelled as Assertion A and the other is labelled as Reason R: 
Assertion A: The dot matrix method of sequence alignment is a very basic method that should be used first, before other more complex methods. Reason R: The diagonal Dot Matrix Display can readily reveal presence of insertions/deletions and direct and inverted repeats that are more difficult to find by the other, more automated methods.
