Question

The final products of digestion should be

• A. Fat soluble and should be able to pass through cell walls.
• B. Water soluble and should be able to pass through cell walls.
• C. Fat soluble and should be able to pass through cell membranes.
• D. Water soluble and should be able to pass through cell membranes.

Answer 1

Answer: (D)

Water soluble and should be able to pass through cell membranes.

• Digestion is catabolic process in the digestive tract where ingested food is converted into simpler, soluble and diffusible substances that can be assimilated by the body and absorbed into the blood from the intestinal walls.
• The end product should be water soluble as it has to combine with the plasma of blood.
• Absorption at intestinal walls is through cell membranes of intestinal cells and walls of blood capillaries.
• So, the correct answer is 'Water soluble and should be able to pass through cell membranes'.
