Digestion of food is considered which type of change?
Answer and explanation
Correct answer: Chemical change
During digestion, enzymes convert complex food substances into simpler new substances. For example, starch is broken down into simpler sugars and proteins into amino acids. Since the chemical composition of food changes and new substances are formed, digestion is a chemical change. In a physical change, only the size, state, or appearance changes while the chemical composition remains the same. Therefore, digestion is not merely a change of state or a reversible change.
