Here are some examples of active transport in animals and humans:
- Sodium-potassium pump (exchange of sodium and potassium ions across cell walls)
- Amino acids moving along the human intestinal tract.
- Calcium ions moving from cardiac muscle cells.
- Glucose moving in or out of a cell.
- A macrophage ingesting a bacterial cell.

What is an example of active transport in an organism?
Active transport is usually associated with accumulating high concentrations of molecules that the cell needs, such as ions, glucose and amino acids. Examples of active transport include the uptake of glucose in the intestines in humans and the uptake of mineral ions into root hair cells of plants.
What are 2 examples of passive transport in living organisms?
The passive forms of transport, diffusion and osmosis, move materials of small molecular weight across membranes. Substances diffuse from areas of high concentration to areas of lower concentration; this process continues until the substance is evenly distributed in a system.
What is the most famous example of active transport?
The Sodium-potassium pump present on the cell membrane is a classic example of active transport, which transports 3 sodium ions outside and 2 potassium ions inside of the cell per ATP.
What are some examples of active and passive transport?
Examples of active transport include sodium-potassium pump, uptake of mineral ions by the roots of the plants, etc. Whereas, the examples of passive transport include the exchange of gases in the alveoli of the lungs and the exchange of nutrients in the kidneys.
What are 3 types of active transport?
Carrier Proteins for Active Transport
There are three types of these proteins or transporters: uniporters, symporters, and antiporters . A uniporter carries one specific ion or molecule. A symporter carries two different ions or molecules, both in the same direction.
Is osmosis active transport?
Osmosis is a form of passive transport when water molecules move from low solute concentration(high water concentration) to high solute or low water concentration across a membrane that is not permeable to the solute. There is a form of passive transport called facilitated diffusion.
Is exocytosis an active transport?
Endocytosis and exocytosis are the bulk transport mechanisms used in eukaryotes. As these transport processes require energy, they are known as active transport processes.
Is exocytosis primary active transport?
Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell. Both endocytosis and exocytosis are active transport processes.
Is diffusion an active transport?
The main difference between diffusion and active transport is that diffusion is a passive transport method in which molecules move across the cell membrane through a concentration gradient whereas active transport requires cellular energy in order to transport molecules against the concentration gradient.
What is active transport in plants?
Active Transport in Plants
Active transport is a mode of transportation in plants, which uses stored energy to move the particles against the concentration gradient. In a plant cell, it takes place in the root cells by absorbing water and minerals.
What is active transport in digestion?
Active transport is a process that is required to move molecules against a concentration gradient. The process requires energy. ... The glucose molecules in the intestine might be in a higher concentration than in the intestinal cells and blood – for instance, after a sugary meal.
How is active transport used in plants and animals?
Active transport in animals
In animals, glucose molecules have to be moved across the gut wall into the blood. ... When the glucose concentration in the intestine is lower than in the intestinal cells, movement of glucose involves active transport. The process requires energy produced by respiration .
