Learn the difference between active and passive transport and get examples of each type of transport process in the cell. Buckle up, as we journey into the heart of our cells to explore this vital process. In cellular biology, active transport is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration —against the concentration gradient

Active transport requires cellular energy to achieve this movement. But how does it happen Active transport is one manner by which cells accomplish this movement by acting against the formation of an equilibrium, typically by concentrating molecules depending on the various needs of the cell, e.g., ions, sugars, and amino acids.
Active transport is a crucial transport mechanism opted by cells to maintain ionic homeostasis in the cytoplasm and regulate the uptake/removal of drugs, nutrients, and waste products.
Active transport is a type of cellular transport in which substances (e.g Ions, glucose, and amino acids) are transported across a biological membrane towards the region that already contains a lot of such substances. In active transport, unlike passive transport, the cell expends energy (for example, in the form of atp) to move a substance against its concentration gradient. For an organism to function, substances must move into and out of cells
Just like a diligent stock replenisher in a supermarket, active transport is constantly at work, moving molecules from a region of lower concentration to a region of higher concentration
