2019-08-20 · Facilitated diffusion is a type of passive transport that allows substances to cross membranes with the assistance of special transport proteins. Some molecules and ions such as glucose, sodium ions, and chloride ions are unable to pass through the phospholipid bilayer of cell membranes . Diffusion is a kind of passive transport.

Passive Transport requires no energy Diffusion movement of molecules Exocytosis remove the material from cell; Active Transport requires Passive and Active Cell Transport Word Wall Cards (Diffusion and Osmosis etc.) Mer information.
Ett exempel på detta är när salt sprider sig jämnt i en lösning. The key difference is really that passive transport does not require energy whereas active transport does. According to wikipedia the GLUT1 you mention is a uniporter that facilitates the diffusion of glucose into the cell, so it is a passive transporter. It does not require energy as it simply helps glucose move down its concentration gradient.

2009-01-11 · Active transport is when molecules that are small, but not lipid soluble go through the carrier proteins in the cell membrane. Bulk transport is when the membrane surrounds large molecules to big to go through the lipid bilayer, to form a vesicle inside which then travels through the cytoplasm.
