Question

_______ is mechanical breakdown of food while _________breakdown occurs in the intestines.


chewing and chemical


mouth and gut


chemical and mechanical

Answer 1

Explanation:

Mechanical breakdown starts with mastication (chewing) in the mouth. Teeth crush and grind large food particles, while saliva initiates the chemical breakdown of food and enables its movement downward. The slippery mass of partially broken-down food is called bolus, which moves down the digestive tract as you swallow.

The pancreas and gland cells of the small intestine secrete digestive enzymes that chemically break down complex food molecules into simpler ones. These enzymes include trypsin (for protein digestion), amylase (for carbohydrate digestion), and lipase (for lipid digestion).

Answer 2

Answer:

digestion is the mechanical breakdown of food while chemical and mechanical breakdown occurs in the intestines.
