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.

Answer:

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

Step-by-step 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.
