What Is The Difference Between Facilitated Diffusion And Active Transport

Two types of diffusion are simple diffusion and facilitated diffusion whereas two types of active transport are primary and secondary active transport.

This differences leads to other aspects of these two types of transport to be different as well. Facilitated diffusion is a type of passive transport that allows substances to cross membranes with the assistance of special transport proteins. Active transport can transport chemicals against their concentration gradients while facilitated transport cannot. The main difference between facilitated diffusion and active transport is that facilitated diffusion occurs through a concentration gradient whereas active transport occurs against the concentration gradient by using energy from atp.

Active transport requires an input of energy usually atp while facilitated transport does not. Simple diffusion facilitated diffusion osmosis and filtration are examples of passive transport. Facilitated diffusion is also a passive transport mechanism that doesn t require any energy but some facilitated diffusion processes can be active. Uptake of glucose in the human intestine works on the principle of active transport.

Differences between active transport and facilitated diffusion. Diffusion is the passive movement of molecules along a concentration gradient of higher concentration to a lower concentration. There is one main difference between facilitated diffusion and active transport. Simple diffusion is a passive transport as thus doesn t require any energy.

Some molecules and ions such as glucose sodium ions and chloride ions are unable to pass through the phospholipid bilayer of cell membranes. Active transport is the movement of particles across a cellular membrane from a lower to a higher concentration by the use of metabolic energy.
