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: -Carbon dioxide is not produced in lactic acid fermentation because no oxygen is used. Lactic acid fermentation only occurs in environments that lack oxygen and involved the splitting of a 6-carbon sugar into two 3-carbon lactic acid molecules. As no carbon is lost, no carbon dioxide can be produced.

Detailed explanation-4: -Fermentation does not involve an electron transport system, and no ATP is made by the fermentation process directly. Fermenters make very little ATP-only two ATP molecules per glucose molecule during glycolysis.

Detailed explanation-5: -Therefore, the products of lactic acid fermentation from one molecule of glucose include 2 ATP, 2 pyruvate, 2 molecules of lactic acid, and 2 NAD+.
