What is alcohol fermentation? Show the net reaction of anaerobic glucose catabolism in yeast. Compare the total ATP outputs of anaerobic vs. aerobic glucose catabolism.

Solutions

Expert Solution

Answer - alcohol fermentation occurs in oxygen deficient conditions or anaerboic cellular respiration in yeast . The end product pyruvate is directed to produce ethanol for energy .

Whereas in caerobic respiration pyruvate isditectrd to form acetyl co A to enter ktebs cycle.

The net equation is -

The net energy yeild of aerobic cellular respiration is 36-38 ATP and that of anaerobic respiration is 2ATP.

In aerobic respiration 2 ATP is produced in glycolysis , 2NADH in pyruvate dehydrogenase complex reaction , 6 ATP , electron transport chain produces 28 ATP

Aerobic respiration is a more efficient pathway of energy generation.

If this helps please give it a positive rating thank you!

Yeast make alcohol in the absence of oxygen by a process called fermentation (i.e., anaerobic respiration). Complete fermentation of one of the sugar glucose (C6 H12 O6) will generate two moles of ethanol (C2 H6 O), two moles of carbon dioxide (CO2) gas, and tow moles of the important molecule ATP (C10 H16 N5 O13 P3), using in cellular transfers. You perform an experiment to make alcohol, so you set up an anaerobic fermentation system using yeast. You add 135...
