BIOLOGY 1 QUIZ REVIEW SHEET
CHAPTER 4.4-4.6 + A LITTLE PHOTOSYNTHESIS REVIEW
Photosynthesis REVIEW first (there will be SOME photosynthesis questions are your quiz next time)
1. What are products of photosynthesis? Sugar and oxygen
2. What organelle does photosynthesis occur in? chloroplast
3. What are the 2 parts of the chloroplast? Thylakoid and stroma
4. Light hits the _______thylakoid___ and electrons get ____excited_______. Water __splits____ to make oxygen for us to
breathe. __ATP____ and ___NADPH______ carry energy into the Calvin cycle to make sugars
5. The Calvin cycle occurs in the ___stroma_______ of the chloroplast. The Calvin cycle has __Carbon dioxide____ enter
the cycle to make ____sugar_______ for its own plant food.
NOW cellular respiration REVIEW
1. What are the final products of respiration? Carbon dioxide (from Krebs), water (From ETC) and ATP
2. What is the equation for respiration? C6H12O6 + O2  CO2 + H20 + energy
3. The energy produced from cellular respiration is used to power ____chemical_____ reactions.
4. Where does cellular respiration occur?
mitochondria
What is made in the powerhouse? ATP
5. Where does glycolysis occur? cytoplasm
6. True or False: Glycolysis does not require oxygen.
TRUE
7. What does glycolysis mean? Splitting of glucose
8. True or False: All living things still use glycolysis to initially get ATP
TRUE
9. What is glucose initially broken down to in glycolysis? Pyruvic acid
10. Glycolysis is followed by the ______Krebs______cycle and the ____Electron______ transport chain when oxygen is
available. When oxygen is not available then the process goes to fermentation which is section 4.6.
11. What are the 2 steps of cellular respiration with oxygen (aerobic respiration)? Krebs cycle and electron transport Chain
12. Aerobic means contains oxygen, anaerobic is without oxygen. Fermentation is anaerobic.
13. How many ATP are made by oxidative (aerobic) respiration? 36
Glycolysis? 2
Krebs cycle? Is used in the ETC
14. Glycolysis breaks glucose down into pyruvic acid which enters the ____Krebs cycle________
C
15. Prior to the Krebs cycle, 1 arbon atom leaves pyruvic acid and forms the molecule ____ CO2___ which is one of the
products of cellular respiration
16. In the Krebs cycle, a 2 carbon molecule enters to cycle and releases 3 products: CO2, NADH, FADH2
17. NADH and FADH2 are formed in the Krebs cycle and enter the ___electron_____ transport chain.
18. NADH and FADH2 are _____energy_____ carrying molecules
19. H diffuse out of the channel protein and ADP makes ____ATP____. ATP IS THE BIGGEST PRODUCT OF CELLULAR
RESPIRATION BECAUSE WE ARE IN THE MITOCHONDRIA!!!!
20. Electrons join with oxygen and H ions to form ___ H20______, one of the other products of cellular respiration that is the
FINAL electron acceptor!
21. So, cellular respiration requires ____oxygen___________in aerobic respiration to make ATP.
22. Living things obtain energy from organic molecules through ___cellular______ _____respiration_____.
23. Without oxygen, _____fermentation______ occurs.
24. In fermentation, pyruvic acid is broken down into ______lactic acid_______ or ____CO2
25. What does lactic acid to do your muscles? Makes sore b/c oxygen is not available
26. In alcoholic fermentation, what are the 2 final products after the reaction? Carbon dioxide and ethyl alcohol
3 PARTS OF CELLULAR RESPIRATION ARE:
1. GLYCOLYSIS
2. KREBS CYCLE—REQUIRES OXYGEN
3. ELECTRON TRANSPORT CHAIN-REQUIRES OXYGEN
FILL IN THE CHART:
GLYCOLYSIS BREAKS GLUCOSE (SOUNDS LIKE GLYCOLYSIS) INTO 2 _____pyruvate___ MOLECULES. THIS
PRODUCES _____2____ ATP AND OCCURS IN THE _______cytoplasm______________ BEFORE PYRUVATE ENTERS THE
KREBS CYCLE IN THE MITOCHONDRIA.
THE KREBS CYCLES IS IN THE MITOCHONDRIAL MATRIX AND PRODUCES ___carbon dioxide____ WHICH WE
EXHALE, AND 3 ENERGY CARRIERS: _____ATP_________, ________NADH_____, AND ________FADH2______- WHICH
ALL HELP MAKE more ENERGY IN THE ELECTRON TRANSPORT CHAIN.
THE ELECTRON _______transport_____________________ CHAIN HAS ELECTRONS GET _________excited_________
AGAIN AND _______H+___ IONS GO IN AND OUT OF THE INNER MITOCHONDRIAL MEMBRANE. THE _______H+___
IONS ADD TO OXYGEN TO MAKE ______H2O_________ WHICH IS A FINAL PRODUCT. THEN ATP, NADH AND FADH2
ARE USED TO MAKE MORE ATP…UP TO _____36_______ ATP.

POWERHOUSE OF THE MITOCHONDRIA!
