1. Write half reactions for the oxidation of 1 molecule glucose and the reduction of oxygen during the aerobic respiration in mammalian cells. Use electron carriers, NAD+/NADH+H+ and FAD/FADH2 for accepting and donating electrons in each half reaction (instead of using "e-" in half reactions). Do not include energy carriers (ATP, GTP) in the reaction.
Define the oxidation state of carbon atom and oxygen atom in the following reactions. How many high energy electrons will be taken away from 1 molecule of glucose when it is completely broken down to carbon dioxide? How many electrons does each oxygen atom accept when it is reduced? (Reactions are not balanced)
C6H12O6 (glucose) ?CO2 Oxidation state of: C ________ ? C _________ How many electrons? ______
O2 ? H2O Oxidation state of: O ________ ? O _________ How many electrons? ______
Write the half reaction of oxidation of glucose (1 molecule) - make sure to include H2O to balance the reaction (review the citric acid cycle)
Write the half reaction of reduction of oxygen (required for 1 molecule of glucose)
Combine the above 2 half reactions to complete the full glucose breakdown reaction during the aerobic respiration.
