The first step of cellular respiration involves the splitting of a glucose molecule. Correct answer: D The splitting or the breakdown of glucose to two pyruvate molecules is glycolysis ,and that is the name for the first step of cellular respiration. Glycolysis takes place in the cytoplasm of the cell.
The first step of cellular respiration takes place in cytoplasm of the cell called glycolysis. Cellular respiration is an aerobic process that requires oxygen and gives off carbon dioxide and it usually involves the complete breakdown of a glucose molecule with the use of oxygen molecule and then produces a net gain of 2 ATP's.
They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration, or converted into starch and stored. Oxygen is produced as a by-product. This process is called photosynthesis.
