Active transport:

a) requires coupling to an energy-releasing system and depends on integral membrane proteins to move solutes across a membrane
b) requires coupling to an energy-releasing system
c) depends on integral membrane proteins to move solutes across a membrane
d) depends solely on diffusion across a membrane from a region of higher concentration to a region of lower concentration


Ans: a) requires coupling to an energy-releasing system and depends on integral membrane proteins to move solutes across a membrane
