Detailed explanation-1: -Fermentation is the opposite process of cellular respiration. Fermentation in yeast produces lactic acid. In the 1st stage of respiration, very little energy is released. Oxygen is a product of cellular respiration.

Detailed explanation-2: -So how does fermentation differ from cellular respiration? Cellular respiration, like burning, results in the complete oxidation of glucose into CO2 and water. Fermentation, on the other hand, does not fully oxidize glucose. Instead, small, reduced organic molecules are produced as waste.

Detailed explanation-3: -Cellular respiration and photosynthesis are direct opposite reactions. Energy from the sun enters a plant and is converted into glucose during photosynthesis. Some of the energy is used to make ATP in the mitochondria during cellular respiration, and some is lost to the environment as heat.

Detailed explanation-4: -In photosynthesis, carbon dioxide and water are used as reactants to produce glucose (sugar) and oxygen gas. In fermentation, the glucose is broken down without the use of oxygen, meaning that it is an anaerobic process.
