Passive transport notes

What is the difference between Active and Passive Transport? Active transport utilizes cellular energy in the form of ATP while passive transport does not..

Passive transport is a process in which a molecule or ion passes through a cell wall via a concentration gradient. It is also known as passive diffusion,

Active vs. Passive Transport! When transport does not require energy, it’s “passive transport”. When it does require energy, it’s called “active transport”. Several transportation strategies require energy and several do not. Osmosis and diffusion are both passive transport; they do not require energy but can only move particles from higher to lower concentration. By using ATP as an energy source, we can move larger or charged particles, and move particles against the concentration gradient.

The key difference between active transport and passive transport is that the active transport moves molecules from low concentration to high concentration

Movement of drugs across biological membranes by passive diffusion, facilitated transport and active transport. Aquaporins allow passage of water and urea but not drugs. #Pharmacology #Nursing #Medicine
