Question
why does the rate of reaction level off at 6.0%
Transcribed Image Text:**Title: Enzyme Activity and Substrate Concentration**
**Experiment 6: Understanding the Effect of Substrate Concentration on Enzyme Activity**
**5. Rank Order the Substrate Concentrations**
_Record your results from highest to lowest enzyme activity._
**6. Which Concentration Produced the Most Gas?**
_Answer: N/A_
**Graph Analysis**
The graph below illustrates the effect of substrate concentration on enzyme activity. It shows that the rate of reaction increases initially with increasing substrate concentration but eventually levels off:
- **Rate of Reaction**: Increases as substrate concentration increases from 0.0% to 6.0%, but plateaus after this point.
- **Substrate Concentration Levels Illustrated**: 0.0%, 0.3%, 0.6%, 6.0%, and 9.0%.
_Visual Description of the Graph_: The graph depicts a curve that rises sharply as the substrate concentration increases up to 6.0%, and then it levels off, indicating that higher concentrations do not further increase the reaction rate.
**7. WHY does the Rate of Reaction Level Off at 6.0%?**
_Answer: N/A_
This educational module provides insights into how substrate concentration affects enzyme activity, with a focus on understanding the relationship between these two factors through visual interpretation of data.
