Question

in active transport, view available hint(s) no energy input is required from the cell. a vesicle inside the cell fuses with the plasma membrane and releases its contents outside the cell. the plasma membrane forms a pocket that pinches inward, forming a vesicle that contains material from outside the cell. molecules move across the plasma membrane by crossing the lipid bilayer directly, rather than by using a transport protein. molecules move across the plasma membrane against their concentration gradient.

Explanation:

Active transport requires energy and moves molecules against their concentration gradient. The first option describes passive transport, the second is exocytosis, the third is endocytosis, and the fourth is simple diffusion.

Answer:

E. molecules move across the plasma membrane against their concentration gradient.
