First, the glucose is broken down. Scientists refer to this step as glycolysis. Then, the second process, aerobic respiration breaks the remains of the glucose down further. During aerobic respiration, oxygen is reduced, donating an electron to hydrogen to form water. The entire process of cellular respiration oxidizes glucose.
What happens during the first stage of respiration? molecules of glucose are broken down into smaller molecules and oxygen is NOT involved and only a small amount of energy is released. What happens during the second stage of respiration? small molecules are broken down into even smaller molecules and these chemical reactions require energy and they release a great deal of energy When you breathe in what do you take in?
