1. Which of the following factors does NOT generally affect the rate of enzyme activity?
Temperature
pH
Substrate concentration
Atmospheric pressure
2. What happens to an enzyme when it is denatured?
It changes its active site shape and loses function.
It becomes more efficient at catalysis.
It binds to more substrates simultaneously.
It converts into a different type of protein.
1. Enzymes are consumed during the reactions they catalyze.
True
False
2. Each enzyme typically catalyzes a wide range of different reactions.
True
False
1. Enzymes are biological that speed up the rate of biochemical reactions.
2. The specific region on an enzyme where the substrate binds is called the .
3. The model describes how an enzyme's active site changes shape slightly to fit the substrate.
1. Explain why maintaining an optimal temperature is crucial for enzyme activity.
2. Describe the effect of extreme pH values on enzyme structure and function.
