Q

What happens when the temperature gets too high (above 37 degrees)?

A

The enzyme is denatured

15
Q

What does denatured mean?

A

When the enzyme starts to unravel and the active site’s shape starts to change so that the substrate is not able to fit - the enzyme won’t be able to function.

16
Q

What are the effects of pH on the enzyme reaction?

A
  • Changes shape of molecule
  • Changes active site
  • Active site no longer works
  • Enzyme can’t perform function
17
Q

Discuss the main metabolic reactions enzymes are involved in

A
  • Build large molecules
  • Change one molecule to another
  • Breakdown of large molecules
18
Q

Describe the structure of enzymes.

A

Enzymes are made out of long chains of amino acids, they have a unique active site and they are folded.

19
Q

What does bile do?

A

It emulsifies lipids into little droplets of fats.

20
Q

Where is protease produced?

A

Stomach, small intestine and pancreas

21
Q

Where is amylase released?

A

Salivary glands and pancreas

22
Q

Where is lipase released?

A

Pancreas
