Enzyme activity and rate of reaction?

Click For Summary
SUMMARY

The relationship between enzyme activity and the rate of reaction is direct; as enzyme activity increases, the rate of reaction also increases, provided that substrate availability is sufficient. Enzyme activity is typically measured by the rate of substrate conversion. While some reactions can occur without enzymes, the presence of enzymes significantly accelerates these reactions until substrate depletion occurs.

PREREQUISITES
  • Understanding of enzyme kinetics
  • Knowledge of substrate concentration effects
  • Familiarity with biochemical reaction mechanisms
  • Basic principles of catalysis
NEXT STEPS
  • Research Michaelis-Menten kinetics for enzyme activity measurement
  • Explore the effects of substrate concentration on reaction rates
  • Learn about enzyme inhibitors and their impact on enzyme activity
  • Investigate the role of temperature and pH in enzyme-catalyzed reactions
USEFUL FOR

Biochemists, molecular biologists, and students studying enzyme kinetics and metabolic pathways will benefit from this discussion.

can someone explain to me the relationship between enzyme activity and rate of reaction?

How are you distinguishing "enzyme activity" from the rate of the reaction? Rate of conversion of substrate is how enzyme activity is typically measured.

that means if the activity of enzyme increase the rate of reaction also increase?

Yes, up until the other necessary substrates are diminished. Of course some reactions can occur without enzymes however enzymes would speed this up
