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? 1. function will be disrupted by adding the urea and regained by removing the urea.2. function will be disrupted by adding the urea, but it will not be regained by removing the urea.3. function will be gained by adding the urea and disrupted by removing the urea.4. function will be unaffected by the addition and removal of the urea.
