Questions and Answers
What is the primary role of enzymes in cellular processes?
What is the primary role of enzymes in cellular processes?
- To lower the activation energy and speed up reactions (correct)
- To increase the activation energy of reactions
- To act as substrates for chemical reactions
- To become denatured under high temperatures
Which of the following best describes denaturation?
Which of the following best describes denaturation?
- The alteration of an enzyme's structure leading to loss of function (correct)
- The process of enzymes binding to substrates
- The increase in temperature that enhances enzyme activity
- The increase in enzyme-substrate concentration
How do varying pH levels affect enzyme activity?
How do varying pH levels affect enzyme activity?
- Enzyme activity is always enhanced at acidic pH levels
- Enzymes function best at very high pH levels only
- Extreme pH levels can lead to denaturation of enzymes (correct)
- Enzymes are not affected by changes in pH
