What happens during digestion? Write a balanced chemical equation for the reaction involved in digestion.
During digestion large complex food particles are broken down into smaller particles. There are various processes that are going on like the breakdown of carbohydrates, fats and proteins simultaneously and a balanced chemical equation for all these processes is not possible.
But we can try to write the equation as
Carbohydrates + Proteins + Fats → (sugar)n + (amino acids)n + Fatty acids + glycerol.
