Based on the results of the experiment, which of the following statements best predicts the effect of urea on the enzyme’s function?

The question is incomplete. The complete question is as follows:

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 urea to the solution. The enzyme did not appear to have a secondary or tertiary structure. The researchers carefully removed the urea from the solution and determined that the enzyme had the original secondary and tertiary structure again.

Based on the results of the experiment, which of the following statements best predicts the effect of urea on the enzyme's function?

Enzymes are made of proteins that are used to increase the speed of the reaction. The enzymes are highly specific in nature and can carry out specific biochemical reactions only.

The specific three dimensional structure of enzyme is important for its biological function. Urea is used as denaturant and may inhibit the functioning of the enzyme. The enzyme can renature by removing the urea from the solution.
