Explanation / Answer

6. All of the above.
It is series of step undergoes in the glycolysis and TCA cycle. Each step enzymes bring down the activation energy lowers

7. Phase 1
Here ATP is consumed. The Glucose to glucose 6-phosphate and fructose 6-bisphosphate to fructose 1,6-bisphosphate steps ATP is used.

8. Phase 3

This is substrate level phosphorylation. 1. ATP is synthesized in the step of 1,3-bisphosphoglycerate to 3-phosphoglycerate and Phosphoenol pyruvate to pyruvate

9. Glyceraldehyde 3 phosphate dehydrogenase

10. Glyceraldehyde 3 phosphate dehydrogenase
The conversion of glyceraldehyde 3-phosphate into 1,3-bisphosphoglycerate (1,3-BPG), a reaction catalyzed by glyceraldehyde 3-phosphate dehydrogenase yield a energy rich NADH molecule.

11. Pyruvate

12. Lactate
In anaerobic condition pyruvate converted into lactate
