Which of the following sentences is nottrue about alcohol dehydrogenase a. The enzyme uses NADH as cofactor. b. The enzyme transfers the hydride, H- between the substrates. c. If yeast alcohol dehydrogenase is reacted with CH3CD2OH, the generated NADH will contain deuterium in the pro-R position. d. If deuterium NAD+ is reacted with CH3CH2OH, the generated aldehyde will contain deuterium. e. If a pro-R deuterium NADH is reacted with Glyceraldehyde-3-phosphate dehydrogenase, deuterium will be remained in NAD+

Question 3 5 pts Which of the following is true about the sensitivity analysis for integer optimization problems? To determine the sensitivity of the solution to changes in model inputs for integer optimization problems, the data must be changed and the problem must be re-solved. The sensitivity analysis is not important for integer problems. Sensitivity reports are readily available for integer optimization problems similar to the linear programming problems. Because of the discrete nature of the integer optimization, Excel Solver...
