Expert Solution
Step 1: Introduction

The biological process of moving molecules or ions across a cell membrane against their concentration gradient is known as active transport. Pumping substances from a region of lower concentration to a region of higher concentration takes energy, frequently in the form of ATP. Numerous physiological processes, including the intake of nutrients and the maintenance of electrochemical gradients in cells, depend on this mechanism. The sodium-potassium pump, which aids in controlling ion concentrations in animal cells is one well-known example.
