Quick Answer. Plants produce oxygen as a byproduct of photosynthesis, the process that plants and other organisms use to create usable energy. Photosynthesis consists of carbon dioxide and water reacting in the presence of energy from sunlight, which produces glucose and oxygen.
This is also called the Krebs cycle or the tricarboxylic acid cycle. When oxygen is present, acetyl-CoA is produced from the pyruvate molecules created from glycolysis. When oxygen is present, the mitochondria will undergo aerobic respiration which leads to the Krebs cycle.However, if oxygen is not present, fermentation of the pyruvate molecule will occur.his is also called the Krebs cycle or the tricarboxylic acid cycle.
