Enzymes

Question 1

Functions

Answer 1

1. Digestion: carbs, fats, protein
2. Blood clotting: fibrin clot catalysed by thrombin
3. Immune system
4. Movement: ATPase activity
5. Nerve conduction: ion pumps for Na and Ca

Question 2

Main properties

Answer 2

1. Catalyse reactions: decrease Ea
2. Specific
3. Unchanged

Question 3

Proteases

ATP Synthase

Answer 3

• Catalyse proteolysis. Example is Serine proteases, which has a reactive serine group that hydrolyses specific peptide bonds
• Proton-driven rotary protein on mitochondrial inner-membrane
