CH 9 Study Guide
1. Define the following words: ADP, ATP, cellular respiration, electron transport chain, photosynthesis, pigment
ADP: Adenosine Diphosphate (two phosphate groups)—an energy molecule
ATP: Adenosine Triphosphate (three phosphate groups)—an energy molecule
Cellular Respiration: process by which cells break down food molecules into energy (ATP)
Electron Transport Chain: in chloroplast and mitochondria—transforms energy from electrons into ATP
Photosynthesis: process that uses the sun’s energy to make glucose
Pigment: a light absorbing compound (chlorophyll)
Stroma: Space inside the chloroplast
2. Draw and describe the three parts of a chloroplast.
Thylakoid: Green disk in the chloroplast
Granum stack: Stack of green thylakoids
3. What is the chemical equation of photosynthesis? What is it written in words?
OR
6 CO2+ 6 H2O + LIGHT ENERGY  C6H12O6 + 6 O2
carbon dioxide + water + sunlight  glucose + oxygen
4. What is the chemical equation of cellular respiration? What is it written in words?
C6H12O6 + 6 O2  6 CO2+ 6 H2O + ATP
OR glucose + oxygen  carbon dioxide + water + sunlight
5. In the first step of photosynthesis (the light reaction):
A. What powers this reaction? Sunlight
B. What is happening in the light reaction? (What was made?) Energized Electrons
C. Where does it occur? Thylakoid
D. What is the byproduct? Oxygen
E. Where do we cash in these electrons? Electron Transport Chain
And who carries the energy for them to the next step? ATP and NADPH
6. In the second step of photosynthesis (the calvin cycle):
A. What powers this reaction? Carbon dioxide and water
B. What is happening in the dark reaction? using energy from ATP and NADPH to create glucose
C. Where does it occur? stroma
D. What is produced? 1 glucose molecule
E. Once the energy is converted, what have our carriers turned into? ADP and NADP
How do we recharge? With sunlight
7. Make a chart of cellular respiration that contains the following: the names of the 3 steps, what happens in each (think
flow-chart), is it aerobic or anaerobic, and how much ATP is produced. (3 rows, 4 columns)

8. What is fermentation? Begins with Glycolysis and will continue if no oxygen is present
What are the two types and what causes each?
Alcoholic: yeast or bacteria must be present—creates alcohol and carbon dioxide as products
Lactic Acid: occurs in muscles with a high need for ATP and a low supply of oxygen
9. How are cellular respiration and photosynthesis related? They are opposites
10. Draw a flow chart of cellular respiration.
11. How much ATP is produced from each stage in CR?
Glycolysis- 2 ATP
Krebs Cycle- 2 ATP
ETC- 32 ATP
Total is up to 36 ATP
12. Know how to label a picture for cellular respiration and/or photosynthesis (coloring activity we did)
13. LOOK UP POWERPOINT (UNIT 5) TO STUDY!
