Description

Glycolysis Worksheet. Please fill in the blanks. 1. Explain why the phosphate end of ATP stores potential energy. Each of the phosphate groups is negatively charged, these negatives repel each other so there would be less energy if they are further apart.

2. Name three kinds of cellular work that your cells perform. Chemical work, Mechanical work, and Transport work

3. Which has more potential energy, ATP or ADP? ATP

4. Explain how respiration (breathing) is related to cellular respiration. When you breathe in you take in oxygen which your cells need for cellular respiration and when you breathe out you get rid of the CO2 that cells produce during cellular respiration.

5. Write the overall reaction for cellular respiration. C6H12O6+6O2-6CO2+6H2O+36ATP+Heat

6. What is an electron transport chain? A series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons across a membrane.

7. What molecule accepts electrons at the end of the electron transport chain? Oxygen molecule

8. What is the literal meaning of the word glycolysis? Sugar splitting or sugar breaking

9. Where in the cell do the cellular respiration reactions take place? In the mitochondria

10. How many ATP are used (changed to ADP) in the first half of glycolysis? Two ATP

11. How many ATP are made from ADP in the second half of glycolysis? Four ATP

12. What is the net gain of ATP for glycolysis? Two ATP

13. How many molecules of pyruvate are made from a single molecule of glucose? Two

14. What molecule stores the high-energy electrons (and hydrogen) removed from glucose in glycolysis? NAD+
