A pump in active transport refers to a protein pump found in cell membranes that uses energy, usually ATP, to actively transport molecules or ions against their concentration gradient. This process allows cells to regulate the concentration of substances inside the cell and is essential for maintaining proper cellular function. Examples include the sodium-potassium pump and the proton pump.
Secondary active transport aka facilitated diffusion [depending on your teacher].
sodium-potassium pump.
Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.
Active transport is the movement of a substance across a cell membrane from low to high concentration with the help of energy.
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
Secondary active transport aka facilitated diffusion [depending on your teacher].
The sodium potassium pump requires ATP - i.e. it is involved in active transport, not facilitated transport.

Sodium pump

Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.
Bulk Transport is an example of active transport. The process by which amoeba engulfs its food and secretes is a type of active transport. Amoeba forms false feet like pseudopodia and engulf food.Active and Passive transport both are related with plasma membrane. Active Transport is the transport of food across plasma membrane with expenditure of energy.
