How are glycolysis, ethanol fermentation, and lactate fermentation all related?Question 2Select one:a.All can proceed in the absence of oxygenb.All require pyruvatec.All three produce NADHd.All three produce carbon dioxide
Solution
Glycolysis, ethanol fermentation, and lactate fermentation are all related in several ways:
a. All can proceed in the absence of oxygen: This is true. All three processes are types of anaerobic respiration, which means they can occur without oxygen.
b. All require pyruvate: This is also true. Glycolysis produces pyruvate, which is then used as a substrate in both ethanol and lactate fermentation.
c. All three produce NADH: This is partially true. Glycolysis does produce NADH, but ethanol and lactate fermentation actually consume NADH. They use it to convert pyruvate into either ethanol or lactate, respectively, thereby regenerating NAD+ in the process.
d. All three produce carbon dioxide: This is not entirely true. Glycolysis does not produce carbon dioxide. However, carbon dioxide is a byproduct of ethanol fermentation, but not lactate fermentation.
So, the most accurate answer would be that all can proceed in the absence of oxygen and all require pyruvate.
