4. Pyruvate is the end-product of glycolysis. Many organisms, such as anaerobic bacteria, can only produce energy (ATP) by glycolysis, therefore, pyruvate has no more potential for ATP generation for these organisms. Rather than simply excrete pyruvate, this molecule is changed to another molecule such as lactate. In these organisms, why do you think pyruvate is changed to lactate and then excreted, rather than simply excreted?
