Answer the following questions in long, detailed answers:

1. What does the word glycolysis mean?

2. a) Where in a cell does glycolysis take place?

b) Is glycolysis considered to be an aerobic or anaerobic stage of cellular respiration?

3. How does glucose enter a cell?

4. Name the enzyme needed in the first step of glycolysis? What molecules bind to this enzyme?

5. Almost all of the glucose that enters a cell is immediately phosphorylated and converted to glucose-6-phosphate. List two reasons why.

6. Why is it necessary that a cell invest 2 ATP per glucose? [Hint: which molecule has more free energy: glucose or fructose-1,6-biphosphate?

7. In step 6 of glycolysis, what molecule is oxidized and what is reduced?

8. Which has more free energy: one molecule of glucose, or two molecules of pyruvate?

9. At the end of glycolysis, what has happened to the energy that was originally in glucose?

10. Write the net chemical equation for glycolysis. Do not include water in the equation.
