What is digestion in laboratory?
INTRODUCTIONDigestion is the process of physically and chemically breaking down food into components that are small enough to be absorbed by the body. The chemical process is controlled by proteins called enzymes. In this lab you will work with two different enzymes that digest carbohydrates and numerous food items.

What is digestion 3rd grade?
This process, called digestion, allows your body to get the nutrients and energy it needs from the food you eat.
How is digestive activity provoked after eating?
The gastric phase accounts for about two-thirds of gastric secretions. Ingested food stimulates gastric activity by stretching the stomach and raising the pH of its contents; this causes a cascade of events that leads to the release of hydrochloric acid by the parietal cells that lower the pH and break apart the food.
What are digestion methods?
The methods include wet decomposition and dissolution of the organic and inorganic samples, in open and closed systems, using thermal and radiant (ultraviolet and microwave) energy. The present and future tendencies for sample preparation also involve on-line decomposition and vapor-phase acid digestion.
Why is digestion needed?
Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.
