yes it does
carbon dioxide
During the Krebs cycle,pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions
During the Krebs cycle, pyruvic acid from glycolysis is used to make carbon dioxide, NADH, ATP, and FADH2.
The citric acid cycle, also known as the Krebs cycle, breaks down pyruvic acid into carbon dioxide and produces NADH, FADH2, and ATP. This cycle takes place in the mitochondria of eukaryotic cells and is an essential part of cellular respiration.
Pyruvic acid enters and carbon dioxide exits.

why pyruvic acid do not move as it is in krebs cycle
When Pyruvic Acid is formed. The pyruvic acid molecules have one of their carbon atoms removed, in the form of CO2. The CO2 will then form coenzymes--> the enzymes that will form will continue on into the electron transport chain.
Pyruvic acid is first converted to acetyl-CoA before entering the Krebs cycle. Acetyl-CoA combines with oxaloacetate to form citric acid, which initiates the Krebs cycle. Throughout the cycle, acetyl-CoA is oxidized to produce energy in the form of ATP, NADH, and FADH2.
if you're talking about after the carbons are exhaled through CO2 the the pyruvate need to give off more CO2 for it to be Acetyl Co-A to pass through the mitochondrial membrane to go through the Krebs cycle. so in the Krebs cycle it's acetyl Co-A. Then it goes to the electron transport chain.
Pyruvic acid cycle does enter the Krebs cycle and is turned into acetyl coenzyme A.
