What are the main outputs of the Krebs cycle per glucose molecule?

Explanation:
The cycle releases carbon dioxide and captures energy in reduced electron carriers and a small amount of direct ATP. Each turn of the cycle starts with one acetyl-CoA and yields one ATP (as GTP), three NADH, one FADH2, and two CO2. Since one glucose molecule produces two acetyl-CoA molecules, the outputs double: two ATP (as GTP), six NADH, two FADH2, and four CO2. This matches the listed totals. Remember, the NADH and FADH2 later drive the electron transport chain to make much more ATP, but the direct outputs of the cycle itself are those amounts.
