What is the difference between monitoring reaction progress over time and measuring initial reaction velocity at varying substrate concentrations?

• A. Monitoring over time measures initial velocity, while initial velocity measures product concentration.
• B. Monitoring over time measures enzyme saturation, while initial velocity measures equilibrium.
• C. Monitoring over time shows changes in product concentration, while initial velocity measures reaction rate at specific substrate concentrations.
• D. Monitoring over time measures substrate concentration, while initial velocity measures time.

Answer: (C)
