1. Where does glycolysis take place in cells? Cytoplasm Mitochondrion Endoplasmic reticulum ribosomes

2. 2. The first step of glycolysis results in the formation of? Glucose-6-Phospate Fructose-6-Phosphate ATP 1,6 Bis-phosphate Glycerate

3. 3. The enzyme that produces G3P is: Hexokinase Adolase PhosphoFructokinase Enolase

4. 4. Which is not part of the net products of Glycolysis? ATP NADH Pyruvate CO2

5. 5. Glycolysis occurs during: Aerobic respiration Anaerobic respiration

6. 6. Which of the following is not a requirement for glycolysis? Oxygen ATP NAD+ Glucose

7. 7. Which of the following is not a product of glycolysis? FADH2 NADH ATP Pyruvate

8. 8. NADH is produced by the oxidation of: G3P ATP Glucose 6-phosphate 2x pyruvate

9. 9. Which enzyme adds a phosphate to Fructose 6-phosphate? PhosphoFructoKinase Hexokinase Adolase Pyruvate Kinase

10. 10. What follows glycolysis in cellular respiration? Krebs Cycle The electron Transport Chain Calvin Cycle All of the above

11. 1. Which of the following statements about the Krebs cycle is most accurate? The Krebs Cycle occurs as part of both cellular respiration and photosynthesis. Oxygen and water are produced in the Krebs cycle. The Krebs cycle is the first step in cellular respiration Not all living things engage in the Krebs Cycle.

12. 2. Which of the following occur during the Krebs Cycle? NAD+ is reduced to form NADH. FADH2 accepts two electrons to form FAD Acetyl-CoA joins with oxaloacetate to form isocitrate Pyruvate is converted into acetyl-CoA
