Question
Chapter 28, Problem 6MCQ
Summary Introduction
Introduction:
The food eaten by the humans is broken down into the constituent units that are absorbed by the cells of the body. The breakdown of food is a combination of mechanical and chemical processes that are involved in the process of digestion. The enzymes chemically break down the bonds in the nutrients to convert them into usable forms.
