Active and passive transport are the two main biological processes that play a crucial role in supplying nutrients, oxygen, water and other essential molecules to the cells along with the elimination of waste products. In essence, active and passive transport work for the same goals/ purposes, but with different movement. Let us see how active and passive transport are different from each other. Difference Between Active And Passive TransportFollowing are the important difference between active and passive transport:
Active TransportThis is the biological process in which molecules move against the concentration gradient and require chemical energy to move biochemical compounds from a lower region to the high region. Therefore, this process uses ATP – Adenosine triphosphate to pump molecules through a concentration gradient. Complex sugar, ions, large cells, proteins and other particles are transported in this process. There are two types of Active transport:
Exocytosis, endocytosis and sodium-potassium pump are a few examples of active transport. The process of endocytosis and exocytosis are utilized by all the cells for transportation of molecules which cannot passively permeate via the membrane.
Main Article: Active Transport. Passive TransportIn this biological process, energy is not required for transporting the molecules, as the biochemicals move from a region of higher concentration to a region of lower concentration. All particles which are easily soluble are transported through passive transport. This process is carried out to maintain the balance and the equilibrium level in a cell. All the waste molecules including, water and carbon dioxide is separated and moved out of the cell using passive transport. Meanwhile, nutrients like oxygen that are functional for the cell are diffused in this process. Osmosis, diffusion and facilitated diffusion are some of the examples of passive transport.

Know more about active and passive transport and the difference between the two only at BYJU’S Biology Frequently Asked QuestionsActive transport moves molecules and ions from lower concentration to higher concentration with
the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy. ATP hydrolysis provides energy for the movement of
molecules and ions across a concentration gradient. The movement of molecules occurs either inside the cells (endocytosis) or out of the cells (exocytosis). 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 is the importance of active and passive transport?Active and passive transport regulate the entry and exit of ions and molecules in a cell. These processes allow only specific materials to cross spontaneously through the cell membrane. Rest need a carrier to pass through the membrane. What are the different types of passive transport?
Passive transport can be of the following different types:
What is the difference between active transport and facilitated diffusion?Facilitated diffusion is down the concentration gradient from higher concentration to lower concentration and does not require energy, whereas active transport is from lower concentration to higher concentration against the concentration gradient and requires energy.
What is the difference between facilitated diffusion and active transport quizlet?Active transport requires energy and moves low concentration to high concentration. Facilitated diffusion is a type of passive transport which moves substances from high to low concentration without using energy.
Which of the following statements concerning facilitated diffusion and active transport is correct quizlet?swell and lyse. Which of the following statements concerning facilitated diffusion and active transport is correct? Both facilitated diffusion and active transport require carrier molecules, but only active transport requires ATP.
