Digestion and Enzymes

Front

What is the function of a buffer system in cells?

Back

A buffer system helps maintain stable pH levels in cells, which is crucial because chemical processes in the cell are sensitive to the concentration of H+ and OH-.

What does pepsin break down?

Back

Pepsin breaks down proteins into amino acids.

Front

Which enzyme in saliva starts the digestion of starch?

Back

Amylase is the enzyme in saliva that begins the digestion of starch.

Front

What are proteins broken down into before absorption in the small intestine?

Back

Proteins are broken down into amino acids before they are absorbed in the small intestine.

Front

What is the primary function of teeth and tongue in digestion?

Back

The primary function of teeth and tongue in digestion is mechanical digestion, which involves breaking down food into smaller pieces.

Front

What is digestion?

Back

Digestion is the process by which food is broken down into smaller components that can be absorbed by the body.

Front

What role do enzymes play in digestion?

Back

Enzymes speed up the chemical reactions that break down food into nutrients.

Front

What is the difference between mechanical and chemical digestion?

Back

Mechanical digestion involves physically breaking down food into smaller pieces, while chemical digestion involves breaking down food into simpler molecules through chemical reactions.

Front

What is the role of hydrochloric acid in the stomach?

Back

Hydrochloric acid helps to create an acidic environment in the stomach, which is necessary for the activation of digestive enzymes like pepsin.

Front

What is amylase and where is it found?

Back

Amylase is an enzyme that breaks down starch into sugars, and it is found in saliva.
