1. Answer the following about cellular respiration. a. Write out the formula for the overall cell respiration reaction.

C6H12O6 + O2 = CO2 + H2O + energy

b. Cellular Respiration involves several redox reactions (oxidation/reduction reaction). Define Oxidation. Define Reduction. Oxidation – Glucose is oxidized and it involves the loss of a hydrogen atom and an electron Reduction – NADH+ is reduced and involves the gain of a hydrogen atom and an electron

c. In the overall reaction of cellular respiration: Which reactant gets reduced? Which reactant gets oxidized?

Oxygen gets reduced and glucose gets oxidized

2. Fill in the table below. Hint – Remember you are following a 6 carbon glucose through this process and glucose is fully oxidized by the end of the Kreb’s Cycle. Follow what the cell does with those carbons in the Kreb Cycle to figure out the end product!
