Active and passive transport are 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. Both processes work towards the same goals but with different movements. The key differences between active and passive transport are:

Active Transport

• Requires cellular energy, usually in the form of ATP, to move molecules against the concentration gradient from lower concentration to higher concentration.
• It is a rapid process that requires carrier proteins.
• Metabolic inhibitors can influence and might make the transportation stop.
• Transpires in a single direction.
• Examples of active transport include phagocytosis, pinocytosis, and the sodium-potassium pump.

Passive Transport

• Does not require cellular energy to move molecules across the cell membrane.
• It circulates from a region of higher concentration to a region of lower concentration.
• It is a comparatively slow process that does not require carrier proteins.
• Transportation is not affected by metabolic inhibitors.
• Transpires in multiple directions.
• Examples of passive transport include osmosis, diffusion, facilitated diffusion, and filtration[[3]](https://www.inspiritvr.com/general-bio/c...
