Unit 5: Cellular Energetics The content covered in this unit can be found in Chapters 8 & 9 of Biology by Miller and Levine. 1. The energy available in food is used to make an energy-rich compound called ______ (3 letters). 2. In what organelle does cellular respiration take place? _____________________ 3. What gas is a reactant in cellular respiration? _____________________ 4. What gas is a product of cellular respiration? _____________________ 5. a) Write the equation for cellular respiration:

b) Identify the reactants in this equation:

c) Identify the products in this equation:

6. Complete the table below. Aerobic Respiration

Anaerobic Respiration

Molecules of ATP produced per molecule of glucose oxidized Process requires Oxygen (Yes or No) 7. Name the two types of fermentation and list their products. 1. 2. 8. How are alcoholic fermentation and lactic acid fermentation different from aerobic cellular respiration?

9. If you place yeast, sugar and water in a sealed bag and place it in the sun, what TWO things will be produced? (One is a liquid, the other is a gas.) 1. 2. 10. In what organelle does photosynthesis take place? _____________________ 11. What gas a reactant in photosynthesis? _____________________ 12. What gas is a product of photosynthesis? _____________________ 13. a) Write the equation for photosynthesis:

b) Identify the reactants in this equation:

c) Identify the products in this equation:

14. What sugar is produced by photosynthesis and used as fuel in cellular respiration? Give its name and its chemical formula: ___________________________________________________ 15. What two colors of light are most effective in the conversion of radiant light energy into the chemical energy of organic compounds? ________________ and ________________ 16. What is the primary difference between an autotroph and a heterotroph?

17. How are cellular respiration and photosynthesis connected?

18. Can photosynthesis occur during daylight and at night? Can aerobic respiration occur during daylight and at night? 19. What is an enzyme and what does it do for a reaction?

The experiment below shows two tomato plants being exposed to light in Step 1. In Step 2, Plant B is covered by a black box to prevent light from entering.

20. In this experiment, what is the control? 21. Use the graph below to explain how the plants grew over the course of 2 weeks.
