Cellular Respiration and Cell Energy Worksheet 1. What is a calorie? A unit of energy 2. How many calories make up 1 Calorie? 1000 calories 3. Cellular respiration begins with a Glycolysis pathway called ? 4. Is the following sentence true or false false? Glycolysis releases a great amount of energy. 5. What is cellular respiration? cells break down simple food molecules such as sugar and release the energy they contain 6. What is the equation for cellular 6CO2 + C6H12O6----> 6CO2 + 6H2O + respiration, using chemical for- energy mulas? 7. Where does glycolysis take place? cytoplasm 8. Where do the Krebs Cycle and electron transport take place? Mitochondria 9. What is glycolysis? The breakdown of glucose by enzymes, releasing energy and pyruvic acid. 10. How does the cell get glycolysis 1. glucose comes from blood to interstigoing? tial flui 11. If the cell uses 2 ATP molecules at the beginning of glycolysis, how does it end up with a net gain of 2 ATP molecules? The cell puts 2 ATP molecues into its "account" to get glycolysis going, when glycolysis is complete, 4 ATP molecules have been produces. Thus a 2 net gain of ATP molecules. 12. What is NAD? electron shuttle compound 1/2 13. What is fermentation? breaking down of pyruvic acid without using molecular oxygen; pyruvic acid is converted to ethanol or lactic acid (in animals) 14. How does fermentation allow gly- With the production of pyruvic acid colysis to continue? 15. Because fermentation does not Anaerobic require oxygen, it is said to be ? 16. What are the two main types of fermentation? alcoholic and lactic acid 17. Because of the final stages of cel- Aerobic lular respiration require oxygen, they are said to be ? 18. Why is the Krebs Cycle also known as the citric acid cycle? Because the first molecule in the pathway is also the last 19. What is the total number of ATP 36 molecules molecules formed during cellular respiration? 2/2
