Which waste product is released during the Krebs cycle per glucose?

Explanation:
During the Krebs cycle, carbon atoms are released as carbon dioxide as acetyl-CoA is oxidized through decarboxylation steps. Each glucose molecule yields two acetyl-CoA, so the cycle turns twice per glucose and releases four CO2 molecules in total. This makes carbon dioxide the waste product associated with the Krebs cycle. Water is produced later in the electron transport chain, not inside the Krebs cycle, and oxygen is consumed there as the final electron acceptor, not produced. Glucose is the fuel that feeding glycolysis earlier, not a waste product of the Krebs cycle.
