How many of each of the following molecules are produced in each step of cellular respiration: ATP, NADH, FADH, and CO2? Please include glycolysis, transition reaction, Krebs cycle, and oxidative phosphorylation.

Glycolysis yields a total of 4 ATP, 2 pyruvates, and 2 NADH molecules. However, since the cell needs to make an initial investment of 2 ATP, it is generally considered that glycolysis only yields 2 ATP, 2 pyruvates, and 2 NADH.
The transition reaction yields 2 molecules of carbon dioxide, 2 NADH, and 2 acetyl Co-A molecules.
Krebs cycle contributes 4 more carbon dioxide molecules, 6NADH, 2 FADH2 and 2 ATP.
Oxidative phosphorylation produces 34 more ATP.
