Which stage of aerobic respiration produces FADH, and NADH and releases CO,?

The Kerb's / Citric Acid/tricarboxylic acid (TCA) Cycle of aerobic respiration produces FADH and NADH and releases CO2

Explanation:

The Kerb's Cycle is termed as the cell's biochemical hub because its main function is to harvest high-energy electrons from carbon fuels.

It is constituted by a series of eight steps of chemical and enzymatic reactions including redox, condensation, hydration, dehydration, decarboxylation etc.

One complete Kerb's Cycle produces 2 carbon dioxide, 1 GTP, 3 NADH, and 1FADH2 molecules. Each glucose molecule yields two acetyl-CoA molecules and hence each glucose molecule requires two Kerb's cycle.
