Please mark me Brainlist

Explanation:

Active transport occurs when molecules are moved across a semi-permeable membrane and UP (against) a concentration gradient.

Answer 2

Active transport takes place against the concentration gradient across the semipermeable membrane (from region of low concentration to a region of higher concentration)

Remember!

Since active transport takes place against the concentration gradient, it requires energy
