Which of the following juices contains the enzyme ptyalin?
Answer Details
The juice that contains the enzyme ptyalin is saliva. Ptyalin, also known as salivary amylase, is an enzyme that breaks down complex carbohydrates into simple sugars. It is produced by the salivary glands and released into the mouth when we eat. Ptyalin begins the process of digestion in the mouth, breaking down starchy foods such as bread and potatoes into smaller, more easily digestible molecules.
Gastric juice is produced by the stomach and contains hydrochloric acid and enzymes that help break down proteins.
Succus is not a specific type of juice. It can refer to any juice that is extracted from a plant or fruit.
Pancreatic juice is produced by the pancreas and contains enzymes that help break down proteins, carbohydrates, and fats in the small intestine.
So, the correct answer is saliva.
