Salivary Digestion and the Role of Amylase

What enzyme in saliva initiates the digestion of carbohydrates?

Amylase (also known as ptyalin)

What is the primary role of saliva in digestion?

To mix food with enzymes like amylase to begin the breakdown of carbohydrates.

What type of carbohydrates does amylase break down?

Complex carbohydrates (starches) into simpler sugars like maltose.

What is maltose?

A disaccharide formed from the breakdown of starches by amylase.

What happens to partially digested starch in the small intestine?

It is further processed by pancreatic amylase and other enzymes, leading to the absorption of glucose.

What are the main components of saliva?

Water, mucus, and enzymes such as amylase and lingual lipase.

What is the function of mucin in saliva?

To lubricate food for easier swallowing.

What role does lysozyme play in saliva?

It helps to prevent infection.

What is the function of lingual lipase found in saliva?

To break down fats, although its role is less significant than that of amylase.

How does mastication contribute to digestion?

It mixes food with saliva, allowing amylase to begin breaking down starches.

What is the end product of carbohydrate digestion that is absorbed in the body?

Glucose (a monosaccharide).

How does saliva aid in the digestion of fats?

Through the action of lingual lipase, which breaks down fats.

What is the significance of amylase in the digestive process?

It initiates the chemical digestion of starches, making them easier to absorb.

What is the relationship between amylase and maltose?

Amylase breaks down starches into maltose during digestion.

What is the overall purpose of salivary digestion?

To prepare complex carbohydrates for further digestion and absorption in the body.
