Food is broken down mechanically and chemically into smaller components that can be absorbed more readily into the bloodstream. This is a form of catabolism in which large food molecules are broken down into smaller ones.
Answer (2)
Answer:Yes, that's correct! The process you're describing is digestion, which involves both mechanical and chemical breakdown of food into smaller, absorbable components. Here's a bit more detail:1. Mechanical DigestionPhysical breakdown of food into smaller pieces (e.g., chewing in the mouth, churning in the stomach).Increases surface area for enzymes to act more efficiently.2. Chemical DigestionEnzymes and acids break down large molecules into smaller, absorbable ones:Carbohydrates → Simple sugars (e.g., amylase breaks starch into maltose, then maltase converts it to glucose).Proteins → Amino acids (e.g., pepsin in the stomach, trypsin in the small intestine).Fats → Fatty acids & glycerol (e.g., lipase action aided by bile).3. AbsorptionSmall molecules (glucose, amino acids, fatty acids) pass through the intestinal lining into the bloodstream or lymphatic system.4. CatabolismDigestion is a form of catabolism (breaking down complex molecules into simpler ones, releasing energy in the process).
