Question

1. in this activity, what was the enzyme represented by? the substrate? the coenzyme? the inhibitor?
2. in trial i, why did the rate eventually decrease? what could have been added to maintain the initial rate?
3. if more substrate(pennies) were present in trial i at the beginning, would the initial rate have been higher? why or why not?
4. if we assume that the enzyme is represented by the hand, what happened to the active site during trial ii?
5. why does an enzyme not work as well if it’s active site is changed?
6. what environmental factors affect enzyme shape?
7. what effect did inhibition have upon the reaction rate?
8. how might chemicals affect you if they acted like the tennis ball (inhibitor) during your bodily reactions?

Explanation:

These questions relate to enzyme activity, a topic in Biology (Natural Science subfield). Here are brief explanations for each:

1.

• Enzyme: Likely a catalyst (e.g., hand in a penny - enzyme simulation).
• Substrate: Pennies (molecule enzyme acts on).
• Coenzyme: May be a helper (e.g., a tool, but context - dependent).
• Inhibitor: Tennis ball (blocks enzyme - substrate interaction).

2.

• Rate decreased: Substrate (pennies) became limited (fewer left to react).
• Maintain rate: Add more substrate (pennies) or enzyme.

3.

• Initial rate: No, initial rate depends on enzyme concentration/activity, not substrate (until saturation, but “initial” implies substrate not yet limiting).

4.

• Active site: In Trial II (with inhibitor), the active site (hand’s “binding area”) was blocked by the inhibitor (tennis ball), reducing substrate binding.

5.

• Active site change: The substrate can’t fit (lock - and - key model) or bind effectively (induced - fit), so catalysis fails.

6.

• Environmental factors: Temperature (too high/low), pH (extreme values), and chemicals (denaturants) alter enzyme shape.

7.

• Inhibition effect: Slows or stops the reaction rate by blocking enzyme - substrate binding.

8.

• Chemicals as inhibitors: They’d block essential enzyme - catalyzed reactions (e.g., metabolism), causing bodily functions to slow or fail.

(Note: Exact answers depend on the specific enzyme - simulation activity’s details, but these follow general enzyme - kinetics principles.)
