Answer 25

Glandular tissue releases hormones and enzymes.

Question 26

What is emulsification in fat digestion?

Answer 26

The process where large lipid droplets are broken into smaller droplets to increase the surface area for lipase action.

Question 27

What is the role of bile in fat digestion?

Answer 27

Bile neutralises stomach acid and emulsifies fat.

Question 28

How does bile aid in fat digestion?

Answer 28

Bile emulsifies fat, increasing the surface area for lipase to act on.

Question 30

What are enzymes?

Answer 30

Enzymes are proteins that act as biological catalysts, speeding up metabolic reactions.

Question 31

What functions do enzymes have in the body?

Answer 31

Enzymes can break down (digest), build up (synthesize), or change molecules.

Question 32

What happens if an enzyme’s temperature is too high or low?

Answer 32

If the temperature is too high or low, the enzyme becomes denatured and can no longer function.

Question 33

What is the optimal temperature for enzyme activity?

Answer 33

Enzymes have an optimum temperature at which they work best, usually body temperature.

Question 34

What is the optimal pH for enzymes?

Answer 34

Enzymes have an optimum pH and will become denatured if they are in the wrong pH environment.

Question 35

What is the rate of enzyme reactions?

Answer 35

The rate of reaction is calculated as: Rate = Change / Time.

Question 36

What is the Lock and Key hypothesis?

Answer 36

The enzyme and substrate have complementary shapes, like a lock and key, allowing them to fit together.

Question 37

What is the active site of an enzyme?

Answer 37

The active site is the region where the enzyme binds to the substrate.

Question 38

What types of enzymes are there?

Answer 38

Amylase, Protease, and Lipase.

Question 39

What does amylase do?

Answer 39

Amylase breaks down carbohydrates into glucose.

Question 40
