Carbon dioxide

Explanation:
Detailed explanation-1: -Krebs cycle produces the following: Two molecules of carbon dioxide are given off. One molecule of ATP is formed. Three molecules of NADH are produced.
Detailed explanation-2: -Step 1: Acetyl CoA (two carbon molecule) joins with oxaloacetate (4 carbon molecule) to form citrate (6 carbon molecule). Step 2: Citrate is converted to isocitrate (an isomer of citrate) Step 3: Isocitrate is oxidised to alpha-ketoglutarate (a five carbon molecule) which results in the release of carbon dioxide.
Detailed explanation-3: -Products and Functions of the Krebs Cycle For one cycle, two molecules of carbon, three molecules of NADH, one molecule of FADH2 and one molecule of ATP or GTP are produced.
