What are the different transport mechanisms for different nutrients? (4) SFSO

Simple diffusion = hydrophobic (fats) cross the hydrophobic part of the membrane. Then passes through the lacteals Facilitated diffusion = monosaccharides, vitamins and minerals are transported by channel proteins helps hydrophilic food pass through the hydrophobic part of the membrane Secondary Active Transport = glucose + amino acids are co-transported with sodium ions (Active translocation) with a transport protein Osmosis: water diffuses across membrane passively as ions and solutes move across in the small and large intestine
