Question

Which of the following statements is true?

a.Transporters change shape when a specific molecule binds to them and use these conformational changes to move it across the membrane while channel proteins provide corridors for specific molecules to pass through.
b.Channels transport substances at a slower rate compared with transporters.
c.Transporters move molecules only via passive transport.
d.Channels transport ions via passive or active transport.

Answer 1

Transporters change shape when a specific molecule binds to them and use these conformational changes to move it across the membrane while channel proteins provide corridors for specific molecules to pass through. Channels transport substances at a slower rate compared with transporters. Channels transport ions via passive or active transport.

Step-by-step explanation:

a.Transporters change shape when a specific molecule binds to them and use these conformational changes to move it across the membrane while channel proteins provide corridors for specific molecules to pass through.

b.Channels transport substances at a slower rate compared with transporters.

c.Transporters move molecules only via passive transport.

d.Channels transport ions via passive or active transport.
