Question

this is one of the most common transport proteins used in active transport. it is called a sodium-potassium pump. if a molecule is moving via active transport, the molecule is moving from... high to low and does not require energy low to high and does require energy rewatch submit

Explanation:

Active transport is a process where molecules move against their concentration gradient. This means from an area of low concentration to an area of high concentration. Since it's against the gradient, energy (usually in the form of ATP) is required. In contrast, passive transport (like simple diffusion or facilitated diffusion) moves molecules from high to low concentration and does not require energy.

Answer:

LOW to HIGH and DOES require energy
