What Is The Main Difference Between Active And Passive Transport

On the other hand passive transport moves biochemicals from areas of high concentration to areas of low concentration.

Active and passive transport are two important biological transport processes that help to move substances such as nutrients oxygen water and other macromolecules within the cell along with the elimination of waste products using different and contrasting mechanisms. The main difference between active and passive transport is that active transport pumps molecules against the concentration gradient using atp energy whereas passive transport allows the molecules to pass the membrane through a concentration gradient requiring no cellular energy. On the other hand passive transport moves molecules and ions from a higher concentration to lower concentration without any energy. Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of atp.

Active transport uses energy and passive transport does not. Active transport can be defined as the movement of molecules across the cell membrane pumping the molecules against the concentration gradient involving atp energy whereas passive transport can be defined as the movement of molecules within and across the cell membrane and through the concentration gradient without using atp energy. Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration. Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration.

Energy in the form of atp is required in active transport. Passive transport is the biological phenomena of transporting soluble and small molecule down the concentration gradient. Active and passive transport are biological processes that move oxygen water and nutrients into cells and remove waste products. So it does not require energy.

The upcoming points will present the substantial differences between active and passive transport. On the other hand passive transport moves molecules and ions from a higher concentration to lower concentration without any energy. How is active transport different from passive transport. The key difference between active transport and passive transport is that the active transport moves molecules from low concentration to high concentration against the concentration gradient via a semi permeable membrane while passive transport moves molecules along the concentration gradient from high concentration to low concentration.
