Question

in active transport. view available hint(s) molecules move across the plasma membrane against their concentration gradient. no energy input is required from the cell. the plasma membrane forms a pocket that pinches inward, forming a vesicle that contains material from outside the cell. a vesicle inside the cell fuses with the plasma membrane and releases its contents outside the cell. molecules move across the plasma membrane by crossing the lipid bilayer directly, rather than by using a transport protein. submit part b a molecule moves down its concentration gradient using a transport protein in the plasma membrane. this is an example of view available hint(s) diffusion. exocytosis. endocytosis. active transport. facilitated diffusion.

Explanation:

Answer:

(a) molecules move across the plasma membrane against their concentration gradient
(b) facilitated diffusion
