Why is digestion of food a chemical change?
Answer and explanation
Correct answer: Complex food substances are converted into new, simpler substances by the action of enzymes.
During digestion, enzymes convert complex food components such as carbohydrates, proteins, and fats into simpler new substances. Digestion is a chemical change because new substances are formed and their properties differ from those of the original food. Option B describes a physical change, such as breaking food into smaller pieces, in which no new substance is formed.
