Tap to flip Answer It is passed out of the body as faeces. Question Is the stomach the only place where food is digested? Tap to flip Answer No. The intestines also play a part in digesting food and absorbing nutrients. Question What is digestion? Tap to flip Answer Breaking down large food molecules into smaller molecules that can be absorbed into the blood. Question What is an enzyme? Tap to flip Answer A biological molecule that acts as a catalyst, speeding up the rate of a reaction. Question Which type of digestion do enzymes speed up? Tap to flip Answer Chemical digestion. Question Which elements make up a carbohydrate molecule? Tap to flip Answer Carbon, hydrogen and oxygen. Question What does the body use protein for? Tap to flip Answer Growth and repair. Question How does the body use fat? Tap to flip Answer It is stored and used for energy. Question Into what do enzymes digest carbohydrates? Tap to flip Answer Sugars. Question Into what do enzymes digest proteins? Tap to flip Answer Amino acids. Question Into what do enzymes digest fats? Tap to flip Answer Fatty acids and glycerol. Question Why are carbohydrates, proteins and fats broken down during digestion? Tap to flip Answer So they become smaller molecules that can be absorbed. Question Is food absorbed without being digested? Tap to flip Answer No. Mechanical and chemical digestion first break food into small molecules, which are then absorbed. Question What does a food test show? Tap to flip Answer Whether a specific type of food is present in a sample. Question What is a reagent in a food test?

Tap to flip Answer Around the body, to where cells need them. Question By what process are some small nutrient molecules absorbed into the blood? Tap to flip Answer Diffusion. Question What do adaptations of the small intestine lining increase? Tap to flip Answer The amount of absorption.

How this deck was checked On 2026-11-02, every card was compared with its source: the lessons of Oak National Academy, a public body funded by England's Department for Education that publishes lessons for the national curriculum. Because the cards come from those lessons, no second source was sought. The comparison was done automatically, not by a teacher, so a card can still be wrong.
