Question 8
Researchers investigated the effect of urea on the three-dimensional structure of a certain enzyme. The researchers dissolved the enzyme in an aqueous buffer solution and added to the solution. The
enzyme did not appear to have a secondary or tertiary structure. The researchers carefully removed the area from the solution and determined that the enzyme had the original secondary and rary structure
again
Based on the results of the experiment, which of the following statements best predicts the effect of urea on the enzymes function?

Answer 1

Urea inactivates the enzyme function via denaturation of its secondary and tertiary function. Without its secondary or tertiary function, it’s 3D structural conformation is altered and it will be unable to perform its function.
