Enzymes

Question 1

What are enzymes

Answer 1

Enzymes are biocatalysts present in the body that speed up the rate of reactions by reducing the activation energy required for it to occur.

Question 2

substrate and product for -
- Proteases
- Amylase
- Lipase
- Maltase
- Sucrase

Answer 2

• Proteins, amino acids
• Starch, glucose
• Lipids, Glycerol+fatty acids
• Maltose, Glucose+Glucose
• Sucrose, Glucose+Fructose

Question 3

How do enzymes work?

Answer 3

Substrate enters an active site in the enzyme which breaks down the substrate into its products. This is done through an enzyme substrate complex - when they bond. The products are then released from the active site.

Question 4

Factors that affect enzymes

Answer 4

• Temperature
• pH
• Concentration of enzyme
• Concentration of substrate

Question 5

What is Denaturation

Answer 5

When the temperature and pH go above their optimum level - causing the enzyme to change shape - and therefore cannot bond with the substrate. This causes it to slow down its activity and denature
