Active transport
That's called the process of absorption. The biological processes that allow absorption are diffusion and osmosis.
Small intestine
Active absorption
Active absorption requires energy in the form of ATP, carrier proteins or channels in the cell membrane for transporting molecules against their concentration gradient, and an appropriate gradient across the membrane to facilitate movement. Additionally, active absorption may involve specific binding sites on carrier proteins for the molecules being absorbed.
No, lipid absorption is primarily a passive process. It occurs through simple diffusion in the small intestine, where lipids are broken down into smaller molecules and then absorbed into the bloodstream. Some specialized transport proteins may facilitate the absorption of certain lipids, but it is not considered active transport.
both high levels of the active form of vitamin D enhance calcium absorption and high levels of estrogen enhance calcium absorption are true
there is have some differeance . 1.
Sulfuric acid does not exhibit significant absorption of ultraviolet (UV) light, and therefore is not considered UV active.
The absorption rate of galactose is higher than glucose because galactose is transported into enterocytes by a secondary active transport mechanism that involves a carrier protein, which allows for faster absorption. In contrast, glucose is primarily absorbed through facilitated diffusion, which is a slower process.
