Active Transport In Plasma Membrane !!hot!! Jun 2026

However, cells cannot rely solely on diffusion. Often, a cell needs to accumulate molecules in high concentrations or pump substances out against their natural gradient. To do this, the cell must expend energy. This process is known as .

Active transport is primarily categorized into two types based on how they utilize energy to fuel the movement of substances. 1. Primary Active Transport active transport in plasma membrane
