Biology

The incorrect statement is about the breakdown of pyruvate not producing CO₂, because CO₂ is indeed released during the complete breakdown of pyruvate in the mitochondria. Specifically, when pyruvate is converted into acetyl-CoA, it releases one molecule of CO₂, and as acetyl-CoA goes through the citric acid cycle, additional CO₂ molecules are released.

The other statements are correct:

Option A:

This statement is correct. Pyruvate enters the mitochondria and is completely oxidized in the Krebs cycle, and water is formed in the electron transport chain which is located in the mitochondria.
