1. What are Lipids?

• They are fatty compounds that perform a variety of functions in our body.
• They serves as the main source of energy in all organisms.
• They are responsible for the structure of the cells.
• They are sold in the market for 40 pesos each.

2. What are the two types of fatty acids?

• Saturated & Non-saturated fatty acids
• Saturated & Unsaturated fatty acids
• Palmitoleic & Linoleic acids

4. They are organic compounds that serves as a genetic information storage molecules and mostly situated in the nucleus.

• Carbohydrates
• Lipids
• Proteins
• Nucleic Acids

5. 'Hydrolase' — this is an example of what?

• Lipids
• Enzymes
• Acids
• Water

6. DNA stands for:

7. What happens to enzymes when their temperature increases above the optimal level?

• Enzymatic activity also increases, which means reactions happen more quickly.
• Denaturation, which means the structure of the enzyme changes.
• It could lead to inactivation due to high temperatures.
• All the above.

8. Which is believed to be better?

• Unsaturated fatty acids
• Saturated Fatty Acids
• Siya

9. This model suggests that the enzyme's active site is more flexible, it changes shape to fit the substrate as it binds.

• Lock and Key Model
• Induced Fit Model
• Shannon-Weaver Model
