The carbon dioxide molecule (CO2) is split into carbon and oxygen during this transition. Some of the oxygen is released and the carbon molecules are mixed with water creating H2O. If you create an equation for the reaction between carbon and water you will see that the product is glucose. Therefore, plants make their food(glucose) from photosynthesis, and release oxygen.
In cellular respiration the carbon atom is split into two pyruvate molecules during glyoclysis. Then, the pyruvate is made into acetyl-CoA. The acetyl-CoA is oxidized in the citric acid cycle to make two molecules of CO2 per cycle. In fermentation glucose, after turning into 2 pyruvate molecules, is converted into a waste product so it can create NAD+ for glycolysis.
How carbon reacts during photosynthesis(light-dependent reaction)
In the light-dependent reaction of photosynthesis it converts light energy into chemical energy, producing ATP and NADPH. ATP and NADPH are both used for the light-independent reactions. This reaction occurs in the stacked thylakoids of the chloroplasts.

Photosynthesis & Respiration
During the light-independent reaction of photosyntehsis synthesized ATP and NADPH are used to provide energy for the synthesis of glucose and other organic molecules from nonorganic carbon dioxide & water. The carbon atoms are "fixed" from CO2 to the carbon skeletons of existing organic molecules. This reaction occurs in the stroma of the chloroplasts.

Carbon atoms are transferred between molecules in a variety of different ways. First, electrons are moved in the electron transport chains within the thylakoid membrane. Every 12 of the three-carbon molecules made, two of them are removed to build organic compounds and 10 continue on in the chain. The removed molecules bond together forming six-carbon sugar like glucose. Photosynthesis removes carbon dioxide from the atmosphere and releases oxygen gas. Cellular respiration uses oxygen and releases carbon dioxide. Some microorganisms go through anaerobic alcoholic fermentation, producing ethyl alcohol and carbon dioxide.
