3. What are digestive enzymes? What are the
enzymes produced by salivary glands, stomach,
pancreas and liver? What are their functions?
Answers
Answer:
An enzyme is a type of protein found within a cell. Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks. Examples of digestive enzymes are:
- Amylase, produced in the mouth. It helps break down large starch molecules into smaller sugar molecules.
- Pepsin, produced in the stomach. ...
- Trypsin, produced in the pancreas. ...
- Pancreatic lipase, produced in the pancreas. ...
- Deoxyribonuclease and ribonuclease, produced in the pancreas.
Amylase is essential for the digestion of carbohydrates. It breaks down starches into sugars. Amylase is secreted by both the salivary glands and pancreas. The measurement of amylase levels in the blood is sometimes used as an aid in diagnosing various pancreas or other digestive tract diseases.There are several enzymes in the liver, including alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), and gamma-glutamyl transpeptidase (GGT). Elevated liver enzymes, found with a blood test, indicate inflamed or injured liver cells.
Enzymes catalyze all kinds of chemical reactions that are involved in growth, blood coagulation, healing, diseases, breathing, digestion, reproduction, and many other biological activities. On biological aspects, enzymes are instrumental substances to many functions in living organisms.
Explanation:
Answer:
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).
