The activity of the cells can only be conducted if there is enough energy that the cell can get from the respiration. It is evident that you really put in the time and effort to understand cellular respiration. The respiratory system Oxygen and carbon dioxide dissolve in water, and most fishes exchange dissolved oxygen and carbon dioxide in water by means of the gills. This process will release the energy. Which part of the body will most likely use the cellular respiration? Acetyl CoA and Oxaloacetic Acid combine to form a six-carbon molecule called Citric Acid (Citrate). In oxidative phosphorylation, enzymes oxidize nutrients resulting in the release of energy. The chemical energy is stored here. Eventually, the electrons powering the pumping of hydrogen into the mitochondria mix with some hydrogen and oxygen to form water and the hydrogen molecules stop being pumped. Cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions. When you chomp food, your body changes the food into a special kind of sugar (like the unique sugar coating on candies) called glucose. This pathway takes electrons from food molecules and transfers them to oxygen, has energy transferred to ATP and arranges molecules into water, carbon dioxide and waste. Khan Academy is a 501(c)(3) nonprofit organization. In C4 photosynthesis, the enzyme PEP carboxylase is used instead of RuBP carboxylase. The lungs are the primary organ and contain numerous sacs known as alveoli, where gas exchange occurs. The oriental hornet (Vespa orientalis) uses the pigment xanthoperin to convert light into electricity, which it uses as a sort of solar cell to power nighttime activity. This is where most of the ATP is made. To aid in gas diffusion within the alveoli, these air sacs are lined with a layer of water. One carbon dioxide molecule and one hydrogen molecule are removed from the pyruvate (called oxidative decarboxylation) to produce an acetyl group, which joins to an enzyme called CoA to form acetyl CoA. Retrieved from https://biologydictionary.net/respiratory-system-fun-facts/. Helmenstine, Anne Marie, Ph.D. "10 Fascinating Photosynthesis Facts."
