If an enzyme in solution is saturated with substrate, the most effective way to obtain a faster yield of products is to a. add more of the enzyme. b. heat the solution to 90°C. c. add more substrate. d. add a noncompetitive inhibitor.

Verified step by step guidance

1. Understand the concept of enzyme saturation: When an enzyme is saturated with substrate, it means that all the active sites of the enzyme molecules are occupied by substrate molecules. This results in the maximum rate of reaction that the enzyme can catalyze under those conditions.
2. Analyze the options: Adding more substrate (option c) will not increase the reaction rate because all the active sites are already occupied. Heating the solution to 90°C (option b) could denature the enzyme, reducing its activity. Adding a noncompetitive inhibitor (option d) would decrease the reaction rate by altering the enzyme's structure and function.
3. Consider the effect of adding more enzyme: Adding more enzyme (option a) introduces additional active sites into the solution. This allows more substrate molecules to bind and be converted into product, thus potentially increasing the overall rate of product formation.
4. Conclude the most effective method: Since the enzyme is already saturated with substrate, the most effective way to obtain a faster yield of products is to add more enzyme molecules, allowing more simultaneous reactions to occur.
5. Choose the correct answer: The best answer is a. add more of the enzyme.
