Bryson · Answer 1

The type of cellular transport that does not involve the flow of particles from an area of high concentration to an area of low concentration is called the active transport.

Cellular transport of ions, gases, nutrients, waste substances and other biomolecules is of two types namely, the passive transport and the active transport. Passive transport is the movement of substances along their concentration gradient from a region of their higher concentration to the region of their lower concentration which does not require energy.

Active transport is the movement of substances against their concentration gradient from a region of their lower concentration to the region of their higher concentration. It uses energy in the form of Adenosine triphosphate (ATP). The best examples being the sodium-potassium pump in the cells and the uptake of glucose in the intestines.

Fleming · Answer 2

In active transport molecules do not flow from an area of high concentration to an area of low concentration. Active transport involves the movement of molecules from a region of lower concentration to a region of higher concentration against a gradient using energy from ATP. For example, the uptake of glucose in the intestine of the human body.
