Aerobic respiration Glucose and oxygen react together in cells to produce carbon dioxide and water and releases energy. The reaction is called aerobic respiration because oxygen from the air is needed for it to work. Energy is released in the reaction.Click to see full answer. In this regard, why do cells need oxygen?Our body cells require oxygen to release energy. The oxygen that we take in during respiration is used to break down the food we eat to release energy from it. When we breathe in oxygen, it diffuses into blood from the lung alveoli. what are the products of aerobic respiration? Cells undergoing aerobic respiration produce 6 molecules of carbon dioxide, 6 molecules of water, and up to 30 molecules of ATP (adenosine triphosphate), which is directly used to produce energy, from each molecule of glucose in the presence of surplus oxygen. Similarly one may ask, how does cellular respiration use oxygen? Cellular respiration is the process cells use to make energy. Cells in our body combine glucose and oxygen to make ATP and carbon dioxide. Oxygen combines with the electrons and two hydrogen ions to make water. Lastly, the hydrogen ions flow through ATP synthase to make ATP.What factors affect cellular respiration? We’ll first review what cellular respiration is, and then explore how three factors affect it: temperature, glucose availability, and oxygen concentration. What Is Cellular Respiration? Right now, you’re probably not running or jumping around, but you’re still using energy. Temperature. Glucose Concentration.
