You have made it through the review.

​

Create an index card to help you on your test!​

​

​Congrats!

Enzymes work in specific conditions.

​

This is known as the optimal condition. ​

​

To find the optimal, go to the highest point on the line graph and then read the number under it. ​

​

​

​

​

​Optimal Conditions

Multiple Choice

What is the optimal pH for this graph?

• 3

• 5

• 7

• 9

Multiple Choice

What is the optimal temperature of this graph?

• 25

• 35

• 45

• 55

Enzymes can become denatured when the temperature or pH is too high.

​

​This means the substrate does not fit anymore and the enzyme loses its structure (shape).

​
