Zoology - Digestion and Absorption Question with Solution | TestHub

Various mechanisms are involved in the absorption of the nutrients:
A. Simple diffusion: Some amount of monosaccharides such as glucose, some amount of amino acids and few electrolytes such as Cl^-.
B. Facilitated transport: Some amount of glucose and some amino acids.
C. Active transport: Monosaccharides such as glucose (most of the absorption), most of the amino acids and electrolytes like Na⁺. Absorption of water depends on the osmotic gradient.
