Question 1 of 190 answered
Why must food be digested before it enters body cells?
Incorrect
Correct answer: To convert large, insoluble molecules into small, soluble ones that can pass through cell membranes
Cell membranes are partially permeable and large molecules such as starch, proteins and fats cannot pass through. Digestion breaks these into small soluble molecules so they can be absorbed into the blood and enter cells.
