Explain the enzyme substrate complex
WebQUESTION:A rate enhancement of 10^6. requires that the enzyme bind its transition state complex with higher affinity than its substrate. Using the Arrhenius equation, shown before this part, find ΔΔG‡cat for a rate enhancement of 10^6 at 298 K. ln (10^6) = ΔΔG‡/ (8.314*298) ΔΔG‡ =34228 J/mol or 34.2 kJ/mol. WebEnzymes. Term. 1 / 6.
