Which of the following is not a fate for pyruvate?

The fate of pyruvate depends on the context of the question options, but common non-fates of pyruvate would include pathways that do not occur under normal metabolic conditions. For example, the option “pyruvate is converted into glucose” is not a direct fate of pyruvate. While pyruvate can be involved in gluconeogenesis (the synthesis of glucose from non-carbohydrate sources), this occurs primarily in the liver and is a separate metabolic process from glycolysis. Thus, pyruvate is not directly converted into glucose but can contribute to the gluconeogenic pathway under specific conditions.
