Why is it necessary to know multiple enzyme kinetic variables to effectively use the Michaelis-Menten or Lineweaver-Burk equations?

• A. Because these equations only require the substrate concentration.
• B. Because these equations can be used without any known variables.
• C. Because these equations are only used for theoretical purposes and do not require known variables.
• D. Because these equations require specific values like vmax and Km to accurately model enzyme kinetics.

Answer: (D)
