1
Q

Where are digestive enzymes produced?

A

By specialised cells in glands and the lining of the gut.

2
Q

What is the general function of digestive enzymes?

A

They breakdown large molecules into smaller molecules.

3
Q

Where is the enzyme amylase produced?

A

Salivary glands.
Pancreas.
Small intestine.

4
Q

What does amylase do?

A

Catalyses the breakdown of starch into sugars.

5
Q

Where does amylase catalyse the breakdown of starch into sugars?

A

Mouth.

Small intestine.

6
Q

Where is the enzymes protease produced?

A

Stomach.
Pancreas.
Small intestine.

7
Q

What does protease do?

A

Calalyses the breakdown of proteins into amino acids.

8
Q

Where does protease catalyse the breakdown of proteins into amino acids?

A

Stomach.

Small intestine.

9
Q

Where is the enzyme lipase produced?

A

Pancreas.

Small intestine.

10
Q

What does lipase do?

A

Catalyses the breakdown of lipids into fatty acids and glycerol.

11
Q

Where does lipase catalyse the breakdown of lipids into fatty acids and glycerol?

A

Small intestine.

12
Q

What conditions do the enzymes in the stomach work best in?

A

Acidic.

13
Q

Approximately what is the pH of the acid in the stomach?

A

pH 2.

14
Q

Where is bile produced?

A

Liver.

15
Q

What does bile do?

A

Acts in the small intestine to neutralise the acid from the stomach.

16
Q

Do enzymes in the small intestine prefer alkaline or acid conditions?

A

Alkaline.

This is why bile is used to slightly alkaline the solution.

17
Q

Name 3 processes where enzymes work inside cells?

A

Enzymes for Respiration.
Photosynthesis.
Protein synthesis.
