Question 9
(a) (i) What is meant by enzyme denaturation? (ii) Other than temperature, give one condition that will denature an enzyme.
Worked Solution & Example Answer:(a) (i) What is meant by enzyme denaturation? (ii) Other than temperature, give one condition that will denature an enzyme. - Leaving Cert Biology - Question 9 - 2021
Step 1
What is meant by enzyme denaturation?
Answer
Enzyme denaturation refers to the alteration of the three-dimensional structure of an enzyme, resulting in the loss of its biological activity. This process occurs when the bonds that hold the enzyme's specific shape are disrupted due to various factors such as extreme pH levels or high temperatures. When denatured, the active site of the enzyme may be changed or destroyed, preventing the substrate from binding effectively.
Step 2
Other than temperature, give one condition that will denature an enzyme.
Answer
One condition that will denature an enzyme, other than temperature, is extreme pH. Abnormal pH levels can disrupt the ionic and hydrogen bonds that maintain the enzyme's structure, ultimately leading to loss of function.
