Question

8 multiple answer 1 point
what conditions may denature an enzyme and/or reduce its activity?
□ exposure to water
□ higher temperatures
□ chemicals and heavy metals
□ lower temperatures
□ changes in ph

Explanation:

• Enzymes are proteins; higher temperatures can break their structure (denature) or reduce activity.
• Chemicals/heavy metals can interact with enzyme structure, causing denaturation.
• pH changes (away from optimal) disrupt enzyme structure/active site, reducing activity or denaturing.
• Lower temps slow enzyme activity (not denature like high temp, but still reduce activity).
• Water is a solvent for most enzymes, doesn’t denature them (enzymes work in aqueous environments).

So correct options: higher temperatures, chemicals and heavy metals, lower temperatures, changes in pH.

Answer:

B. higher temperatures, C. chemicals and heavy metals, D. lower temperatures, E. changes in pH
