Final answer:
The Krebs cycle will not take place if pyruvate is not produced, as pyruvate is essential for the cycle to occur and for the production of ATP, citric acid, and carbon dioxide.
Step-by-step explanation:
The Krebs cycle will not take place if pyruvate would not be produced. The Krebs cycle is dependent on pyruvate as it is the compound that enters the mitochondria to proceed into the cycle. Without pyruvate, the Krebs cycle cannot occur and the production of ATP, citric acid, and carbon dioxide will be compromised.
