Question 1

What is digestion?

Answer 1

The break down of large insoluble molecules into soluble substances that can be absorbed into your blood

Question 2

What are the 3 types of enzymes used in digestion?

Answer 2

Amylase
protease
lipase

Question 3

Amaylase

• Where are they made in the body?
• Which reaction each emzyme catalysts?
• Where reaction works in the digestive system?

Answer 3

• salivary glands and pancreas
• Digests starch break it down to sugar
• small intestines and mouth

Question 4

Protease

• Where are they made in the body?
• Which reaction each emzyme catalysts?
• Where reaction works in the digestive system?

Answer 4

• stomach, pancreas, small intestines
• breaks down protein to amino acid
• stomach and small intestines

Question 5

Lipase

• Where are they made in the body?
• Which reaction each emzyme catalysts?

Answer 5

• pancreas and small intestines
• Lipids you eat are broken down into fatty acids and glycerol in the small intestines and pass into your bloodstream to be carried around your body to the cell that needs them.
• small intestines

Question 6

What happens to the activity of an enzyme as the temperature increases?

Answer 6

As the pH increases, enzyme activity increases until it reaches an optimal point in which enzymes denature and as the pH increases enzyme activity decreases. pH can make and break intra-molecular bonds changing the shape of the enzyme as a result its effectiveness
