REVIEW: Which of the four major biological macromolecules can be easily identified by the nitrogen base found in its structure?

• Carbohydrate
• Protein
• Lipid
• Nucleic Acid

After the enzyme and substrate bind together and perform the reaction, what does the substrate become?

• another substrate
• an enzyme
• a product
• an active site

The enzyme amylase helps the body breakdown starch in food and functions optimally at body temperature (37 C). A young child runs a fever of 40C for 24 hours.  Predict the effect this may have on his digestion.

• Digestion will increase because starch molecules are colliding faster with the enzyme.
• Digestion will increase because enzyme activity improves at higher temperature.
• Digestion will decrease because starch molecules are colliding faster with the enzyme.
• Digestion will decrease because the shape of the enzyme is altered past optimal temperature.

• enzyme substrate complex.
• reaction site.
• active site.
• lock and key.

What makes an enzyme specific?

• Size
• Shape
• Name
• Location it is found in
