They all require ATP in order to occur, and they all involve cell action.
In the intestines, cells use active transport to pump nutrients such as glucose and amino acids from the intestinal lumen into the bloodstream. In the kidney, cells actively transport ions and small molecules from the blood into the nephron tubules for excretion in urine. In nerve cells, active transport is used to maintain the concentration gradients of sodium and potassium ions across the cell membrane, essential for nerve signaling.
A) Active transport through special transport proteins in the plasma membrane. ATP causes these proteins to change shapes and move materials from low to high concentration. B) Bulk transport - moving large particles through the membrane by endocytosis or exocytosis.
Active transport is the process of moving solutes against their electrochemical gradient. This is essential to maintain the intracellular ionic composition of cells and to import solutes that are at a lower concentration out side the cells and to import soultes that are at a lower concentrion outside the cell than inside. (i) Coupled transporters couple the uphill transport of one solute across the membrane to the downhill transport of another. (ii) ATP-driven pumps couple uphill transport to the hydrolysis of ATP. (iii) Light-driven pumps, which ae found mainly in bacterial cells, couple uphill transport to an input of energy from light.Your three types of Active Transport is therefore Coupled Transporters, ATP-driven pumps, and Light-driven pumps.
when molecule travels from a higher concentration to a lower concentration through a concentration gradient.It is known as passive transport. Active transport refers to when molecule travels from a region of lower concentration to a region of higher concentration against the concentration gradiet. Transport of protein is an active transport. Fit it in the sentence your way
Well, darling, we've got primary active transport where molecules move against the concentration gradient using ATP, secondary active transport where molecules hitch a ride with another molecule moving down its gradient, and finally, good old vesicular transport where large molecules are engulfed by a vesicle and transported across the cell membrane. Hope that clears things up for you, sugar.

Active transport refers to when molecule travels from a region of lower concentration to a region of higher concentration against the concentration gradiet. Transport of protein is an active transport. Fit it in the sentence your way
In primary active transport, the transport protein gets phosphorylated; in secondary active transport, the transport protein is not phosphorylated

Transport
Yes, exocytosis is a process in which cells can expel waste or other materials from the cell by releasing them through vesicles merging with the cell membrane. This allows the cell to remove unwanted substances and maintain internal balance.
