Question 14 of 19 Map Sapling Learning macmillan learning In yeast, ethanol is produced from glucose under anaerobic conditions. What is the maximum amount of ethanol (in millimoles) that could theoretically be produced under the following conditions? A cell-free yeast extract is placed in a solution that contains 3.50 x102 mmol glucose, 0.40 mmol ADP, 0.40 mmol Pi, 0.80 mmol ATP, 0.20 mmol NAD, and 0.20 mmol NADH. It is kept under anaerobic conditions Number mmol Under the same conditions, what is the theoretical minimum amount of glucose (in millimoles) required in the solution to form the maximum amount of ethanol? Number mmol

Explanation / Answer

the reaction is

C6H12O6 + 2 ADP + 2 Pi -----------------> 2 C2H5OH + 2 ATP + 2 CO2

ADP = 0.4mmol

Pi =0.4 mmol

glucose = 350 mmol

limiting reagent is ADP or ATP. so

mmol of ethanol formed = 0.40 ------------------> answer 1)

1 mol gluocose ---------------> 2 moles ethanol

glucose needed = 0.40 / 2

                        = 0.20

glucose needed = 0.20 mmol   -----------> answer 2
