Photosynthesis and Cellular Respiration Exam Study Guide – General Biology 2016
Answer all questions on a SEPARATE SHEET OF PAPER!
1. Draw the structure of ATP and ADP. Where is the energy from food stored in ATP?
How does ADP get turned back into ATP?
2. Where in a molecule is energy stored? How can a molecule release this energy?
3. What three types of carbon based molecule do organisms break down in order to produce
ATP. Which of these three is the most commonly used for this purpose? How many
ATP per molecule?
4. What is the purpose of photosynthesis? Where in plant cells does it occur?
5. Why are plants considered producers?
6. What is chlorophyll? Where is it located inside of a plant cell? What is its function?
7. Draw the internal structure of a chloroplast. Label a thylakoid, the grana and the stroma.
8. Write out the balanced equation for photosynthesis. Underline the products and circle the
reactants.
9. What is the overall purpose of the light dependent reactions in photosynthesis? Where do
the light dependent reactions happen in the chloroplast? Write out the reactants and
products of the light dependent reactions.
10. What is the overall purpose of the light independent reactions in photosynthesis? Where
do the light independent reactions happen in the chloroplast? Write out the reactants and
products of the light independent reactions. Where does the energy necessary for the
light independent reactions come from?
11. What is the purpose of cellular respiration? Where in eukaryotic cells does it occur?
12. What is the function of glycolysis? Where in the cell does glycolysis happen? Is
glycolysis aerobic or anaerobic? How can you tell?
13. Write out the balanced equation for cellular respiration. Underline the products and circle
the reactants. How is this equation similar to the equation for photosynthesis?
14. What is the overall purpose of the Krebs cycle in cellular respiration? Where does the
Krebs cycle happen in the mitochondria? Write out the reactants and products of the
Krebs cycle.
15. What is the overall purpose of the electron transport chain? Where is the electron
transport chain in the mitochondria? Write out the reactants and products of the electron
transport chain.
16. Do plants do cellular respiration? Explain your answer.
