Question

Enzymes can be changed by temperature or pH

true

false

Answer 1

Enzymes can denature (change shape) when the temperature gets too high. Enzymes can only be used once in a chemical reaction. Extreme pH can denature enzymes.

so true... i thinks...

Answer 2

Step-by-step explanation:

Temperature: Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity.
