requires the input of energy and a carrier protein to move nutrients across a concentration gradient
passive
active transport -taking anatomy and physiology II
That's called the process of absorption. The biological processes that allow absorption are diffusion and osmosis.
a protein carrier and energy
Active transport
Small intestine
Active absorption
it is absorbed by 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.
Diffusion,ion exchange and mass exchange is the mechanism of active absorption of minerals in plants.
I believe it's active transport. active transport is correct.
