Which of the following is the overall reaction for ethanolic fermentation (the creation of 2 ethanol from 1 glucose)?
a) glucose + 2 ADP + 2 Pi + 2 NAD+ - - - - > 2 pyruvate + 2 ATP + 2 H2O + 2 NADH + H+
b) glucose + 2 ADP + 2 Pi + 2 NAD+ - - - - > 2 ethanol + 2 ATP + 2 H2O + 2 NADH + H+
c) glucose + 2 ADP + 2 Pi + 2 NAD+ - - - - > 2 ethanol + 2 CO2 + 2 ATP + 2 H2O + 2 NADH + H+
d) glucose + 2 ADP + 2 Pi + 2 H+ - - - - > 2 ethanol + 2 CO2 + 2 ATP + 2 H2O
Homework Answers
The overall reaction is
glucose + 2 ADP + 2Pi + 2NAD+ ----> 2 ethanol + 2CO2 + 2ATP + 2H2O + 2NADH+ 2H+

8. Requirement for Phosphate in Ethanol Fermentation In 1906 Harden and Young, in a series of classic studies on the fermentation of glucose to ethanol and CO2 by extracts of brewer's yeast, made the following observations: 2) During fermentation under these conditions, ethanol, CO2, and a hexose bisphosphate accumulated. Yeast produces ethanol and CO2 by fermentation. NADP+ will accumulate if no ethanol fermentation occurs in anaerobic conditions. Hence, no new NAD+ would be available for further glycolysis. Pyruvate is converted...
