Date: Period: 12 4 9 10 Glucose, or any carbon-based molecule, can be burned in oxygen (oxidized) to produce carbon dioxide and water Combustion reactions release large amounts of energy. However, the energy release is uncontrolled. An organism would not be able to handle all that energy at once to do the work of the cell. Cellular respiration is essentially the same reaction as combustion, but the oxidation of glucose occurs in several controlled steps. The same amount of energy is ultimately releed but it is oradually released in small, controlled amounts. High potential energy molecules of ATP are produced while the carbon atoms are used to form various other molecules of lower potential energy. Each of these stens is rotalused by an enzyme specific to that step. Model 1 illustrates the ideal circumstances for cellular respiration. In cama situations, however, one glucose molecule may not result in 38 ATP molecules being produced 5. Consider Model 1. Besides ATP, what other molecules appear to be high potential energy molecules (free energy carriers) during cellular respiration?

Answer 1

At the time of cellular respiration, glucose molecule is transformed into carbon dioxide and H2O, energy being discharged and stocked within higher potential energy molecules of ATP. The glucose molecule here is considered to be a high potential energy molecule whereas the carbon dioxide is considered to have lower potential in terms of energy. In order for the hydrogen ions to cross the mitochondria, required pump of energy is needed by the high potential energy electron carriers, further carried by NADH and FADH2.
