Q. Why is active transport considered important?
A) Because material is transported from higher concentration to lower concentration
B) Because material is transported from lower concentration to higher concentration
C) Because it increases diffusion coefficient
D) Because it does not use ATP
Explanation
Active transport is a fast process comparative to passive transport and it occurs against the concentration gradient, i.e., material substances are transported from a region of lower concentration to higher concentration. While in diffusion, transport of substances occur along the concentration gradient
