ENZYMES

Question 1

Enzymes

Answer 1

• proteins
• end in -ase
• Speed up reactions by lowering the activation energy required for reactions to occur

Example: Uroporphyrinogen decarboxylase: 2-3 BILLION years

Question 2

Types of Enzymes

Answer 2

VERY specific, each enzyme has only 1 function.
- Active site where reactants can be brought together to react
- Enzymes and substrates: lock and key, they bond until the reaction is done, and substrates are converted to products.
- products released and enzymes are free to start again

Question 3

Enzyme Action

Answer 3

Can be affected by any variable that influences protein and chemical reactions .
- pH
- temp

Acidic Enzyme: 6: stomach
Basic Enzyme: 9: intestine
