Question

amino acids are absorbed from the gi tract through
a facilitated transport
b simple diffusion
c active transport
d osmosis

Explanation:

Amino acids are absorbed against their concentration gradient in the gastrointestinal (GI) tract. Active transport is the process that moves substances against their concentration gradient with the use of energy (ATP). Facilitated transport moves substances down their concentration gradient with the help of carrier - proteins but without energy input. Simple diffusion is the passive movement of substances down their concentration gradient. Osmosis is the diffusion of water across a semi - permeable membrane.

Answer:

C. Active transport
