Ans.) Food is cut into smaller pieces by cutting and maxitating action of teeth. This process helps in increasing surface area of food to come in contact of enzymes that is acting on it which is required for digestion of macromolecules. By cutting food into smaller pieces decreases the digestion time and and increases efficiency of digestion. As smaller the size of food particles, more is surface area available for enzymes to act upon it, hence digestion occurs more efficiently.
Why is it better to eat food in pieces rather than whole? In terms of surface...
