e G uncat G cat ( ) - /RT = catalyzed rate uncatalyzed rate substrate product G E cat uncat 18.0 kcal/mol 7.89 kcal/mol 4.52 kcal/mol e G uncat G cat ( ) - /RT = catalyzed rate uncatalyzed rate CHEMISTRY 365 BIOCHEMISTRY SOME PRACTICE FOR EXAM 2 1. Based on the reaction energy diagram shown, calculate the rate of the catalyzed reaction compared to the uncatalyzed reaction at 37.0 o C. 2. An enzyme lowers the activation energy of a reaction from 36.9 kcal/mol to 20.0 kcal/mol at 37.0 o C. Calculate the rate of the catalyzed reaction compared to the uncatalyzed reaction. 3. An enzyme speeds up a reaction by a factor of 36,500 over the uncatalyzed reaction at 37.0 o C. How much has the enzyme lowered the activation energy for the reaction in kcal/mole? 4. A student creates a standard plot for a spectrophotometric determination of monosaccharides. They report the slope and intercept in their Abstract as 445 and -0.044 respectively. What concentration units did they use for the standard solutions? 5.
