BIOLOGY Proteins as enzymes

Talya Cankan 9-F/287

Enzymes:

Denaturatıon:

• Catalysts for biological reactions (speed up)
• Most are proteins
• Lower the activation energy
• Increase the rate of reaction
• Activity lost if denatured
• May be simple proteins

Denaturation happens when enzyme looses it shape because of heigh temperature and it not works.

Namıng Enzymes:

Factors affectıng enzyme actıvıty:

Naming the enzymes based on:

• what it reacts with
• how it reacts
• add -ase ending

• Amount of water
• pH value
• Temperature
• Surface area
• Enzyme amount
• Pressure
• Substrate amount

Enzyme actıon:

Enzymes have unique substrate and it not works without them. They have active site and that active site connects with it substrate then enzyme can work.

- Enzymes work better in 36 cantigrat degrees
