4. What are the results of the kreb cycle? 2 ATP Molecules 6 NADH Molecules 2 FADH2 Molecules 4 CO2 Molecules

5. 1,2 What kind of reactions does photosynthesis consist of? Light Dependent and Light Independent Reactions

6. 1,3 during which process are oxygen molecules directly involved during cellular respiration? Accepting electrons at the end of the electron transport chain.

7. 1,4 Label and draw the diagram of the mitochondria

8. 2,1 Compare Oxidation and Reduction Oxidation: loss of electrons, gain of oxygen, loss of hydrogen, results in many C-O bonds, results in compound with lower potential energy Reduction: gain of electrons, loss of oxygen, gain of hydrogen, results in many C-H bonds, results in a compound with higher potential energy

9. 2,2 Explain photophosporylation in terms if chemiosmosis 1- Involves electron transport chain embedded in the membrane of the thylakoids 2- Energy is released when electrons are exchanged from one carrier to another 3- Released energy is used to actively pump hydrogen ions into the thylakoid space 4- Hydrogen ions come from the stroma 5- Hydrogen ions diffuse back into the stroma through the channels of ATP synthase 6- ATP synthase catalyses the phosphorylation of ADP to form ATP

10. 2,3 Which of the following features is/are present in mitochondria but not in choloroplast? I- DNA and ribosomes II- outer and inner membranes III- cristae III only

11. 2,4 Draw and Label the structure of a Chloroplast

12. 3,1 Define Cell Respiration The controlled release of energy from organic compounds in cells to form ATP (with or without oxygen)

13. 3,2 State 4 facts of light independent reactions 1- occurs with in the stroma 2- ATP and NADPH are produced by light dependent reactions to provide energy for light independent reactions 3- The result of light independent reactions is glucose 4- These reactions begin and end with the same substance

14. 3,3 What chemical substances are used during the manufacture of organic molecules in photosynthesis? • Hydrogen • ATP • Carbon Dioxide

15. 3,4 What process is this diagram showing? Glycolysis

16. 4,1 When fructose- 1, 6- bisphosphate splits into two 3- carbon sugars called glyceraldehyde-3-phosphate, the process involves what? Lysis

17. 4,2 Light dependent reactions consist of two photosystems. What is the order these photosystems come in (Photosystem 1 and Photosystem 2) and how many nm are the photons when each phosystem accepts them? • Photosystem 2 then Photosystem 1 • Photosystem 2 accepts the photons at • 680 nm • Photosystem 1 accepts the photons at • 700 nm

18. 4,3 What is the first identifiable product of carbon dioxide fixation in photosynthesis? Glycerate 3- phosphate (GP)

19. 4,4 When acetyl coa from the link reaction it combines with a 4- carbon compound called what? Oxaloacetate

20. 5,1 Where in the mitochondria does the link reaction take place? Matrix of the Mitochondria

21. 5,2 When photolysis occurs and splits the water molecules during light dependent reactions what are formed? • Electrons • Hydrogen Ions • Oxygen

22. 5,3 State two factors in the environment of a plant, apart from light intensity, that can affect the rate of photosynthesis in the plant. 1- temperature 2- CO2 concentration

23. 5,4 When triose phosphate leaves the cycle they become sugars that are used to make what? Complex Carbohydrates
