The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Glycolysis**: Glycolysis is the metabolic pathway that breaks down glucose (a six-carbon sugar) into smaller molecules. The term "glycolysis" can be split into "glyco," meaning glucose, and "lysis," meaning breakdown. 2. **Location of Glycolysis**: This process occurs in the cytoplasm of nearly all cells, whether they are aerobic (requiring oxygen) or anaerobic (not requiring oxygen). 3. **End Product of Glycolysis**: The main product of glycolysis is pyruvic acid (or pyruvate). During glycolysis, one molecule of glucose is converted into two molecules of pyruvic acid. 4. **Intermediate Products**: While glycolysis involves several intermediate compounds, such as phosphoenolpyruvate (PEP), these are not the final products of the glycolytic pathway. PEP is converted into pyruvic acid in the final step of glycolysis. 5. **Other Options Analysis**: - **Acetyl-CoA**: This compound is formed from pyruvic acid after glycolysis, during the transition to the Krebs cycle, so it is not the direct product of glycolysis. - **Citric Acid**: This is produced in the Krebs cycle, which occurs after glycolysis, and is not a product of glycolysis itself. 6. **Conclusion**: Based on the breakdown of glucose and the analysis of the options provided, the correct answer to the question is that glucose is converted into pyruvic acid during glycolysis. **Final Answer**: Pyruvic acid. ---
