Question

Why protein cannot diffuse through the wall of villus

Answer 1

Villi and microvilli are adapted to absorption by: They give a very large surface area for faster diffusion of food molecules Each villus contains a large network of blood capillaries transporting more blood, thus faster diffusion Each villis is one cell thick, reducing the diffusion distance and making it faster Each ...

Answer 2

Answer:

proteins are complex of amino acids

Explanation:

where villi in humans can absorb simpler to simplest substances.

due to which proteins are breakdown into fatty acids and these get covered by fat layer around it(chylomicrons) which are now ready to absorb.fat layer is to cross over walls and protect the amino acids.

once they cross the wall they get into blood stream.
