oxidation of pyruvate

|
|
alcohol fermentation
|
|
|
lactic acid fermentation
|
Detailed explanation-1: -Final answer: Carbon dioxide is not released in lactate fermentation.
Detailed explanation-2: -So photosynthesis is the only process among the given option that does not produce carbon dioxide instead uses it to produce food.
Detailed explanation-3: -Reduction of pyruvate using the electrons carried by NADH produces lactate (i.e. lactic acid). While this is similar to alcoholic fermentation, there is no carbon dioxide produced in this process.
Detailed explanation-4: -Answer and Explanation: Carbon dioxide is not produced in lactic acid fermentation because no oxygen is used.
Detailed explanation-5: -Fermentation produces carbon dioxide gas – about 40 times the volume of grape juice. Excessive carbon dioxide in the air can cause headache, sweating, rapid breathing, increased heartbeat, shortness of breath, and dizziness.
