In active transport, View Available Hint (s) In active transport, molecules move across the plasma membrane by crossing the lipid bilayer directly, rather than by using a transport protein. 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 against their concentration gradient.

In active transport, molecules move across the plasma membrane against their concentration gradient.

Explanation:

One of the methods through which molecules move into the cells is known as the active transport. Active transport can be described as a phenomenon in which molecules move from lower concentration towards higher concentration across the membrane of the cell. Hence, it is a phenomenon which occurs against the concentration gradient.

FoR active transport to occur, the cell needs energy which is usually utilized in the form the ATP.
