Question

Choose the statement that best describes the effects of a higher or lower pH on enzymes.

- Affect the likelihood for the substrate to find the active site of the enzyme.
- Affect the likelihood for the reaction to take place.
- Speed up the reaction.
- Affect the structure of the enzyme and reduces the enzyme activity.
- The natural configuration of the enzyme is destroyed.

Answer 1

Higher or lower pH affect the structure of the enzyme and reduces the enzyme activity.

Step-by-step explanation:

• Enzymes are biological molecules that speed up the rate of chemical reactions.
• Enzyme activity is affected by several factors which include temperature, pH, and enzyme inhibitors.
• Enzymes work on specific molecules known as substrates. They are substrate-specific.
• Enzymes work best at optimum pH and temperature.
• Higher or lower pH affects the structure and charges of an enzyme thus affecting enzyme activity.
• Lower temperature deactivates the enzymes while higher temperatures denature the enzymes.
