Question

Match the following absorption process with their substrate.

• A. Glucose
• B. Water
• C. Fatty acid

Answer 1

• Absorption of nutrients in small intestine takes place mostly due to concentration gradient.
• Simple diffusion, facilitated diffusion, active transport and osmosis are the processes which help in the absorption of nutrients.
• Fatty acid and glycerol absorption takes place via simple diffusion.
• Glucose, fructose, galactose and amino acids are absorbed via facilitated diffusion.
• Water is absorbed through osmosis.
