1. In your respiration packet, answer the six questions on page one. Warm-up

2. The “A” in ATP stands for Adenosine. It is built by Adenine and Ribose. The “T” stands for Tri- The “P” stands for Phosphate. Review of warm-up 3 Phosphates are present in one ATP molecule.

3. How would you represent the equation in which ATP becomes ADP? ATP  ADP + P i ReactantProducts

4. With a neighbor, fill in the steps in this cycle of Photosynthesis and Respiration. We will check your answers when you are done! Photosynthesis and Respiration Page 2

5. Two types of Respiration 1.Anaerobic Cellular Respiration 2.Aerobic Cellular Respiration

6. Glycolysis takes place in the cytoplasm ATP PP ADP ATP = -2

7. P P Glycolysis takes place in the cytoplasm PP NAD + NADH = +2

8. P P Glycolysis takes place in the cytoplasm PP ADP ATP ATP ATP = +2

9. Glycolysis takes place in the cytoplasm P P ADP ATP ATP ATP = +2 Pyruvate

10. What is the net gain of energy in Glycolysis? ATP = + 2 NADH = + 2

11. Moving on to the Krebs Cycle Enjoy this video clip, and jot down a summary of Krebs’ and Chance’s research. Pay attention to the significance of both scientist’s discoveries.

12. The Krebs Cycle takes place in the Mitochondrion NAD + NADH CoA Acetyl CoA

13. The Krebs Cycle takes place in the Mitochondrion CoA Citrate

14. The Krebs Cycle takes place in the Mitochondrion NAD + NADH

15. The Krebs Cycle takes place in the Mitochondrion NAD + NADH

16. The Krebs Cycle takes place in the Mitochondrion P ADP ATP NADHNAD +

17. The Krebs Cycle takes place in the Mitochondrion FADH FADH 2

18. How much energy did the Krebs Cycle produce? NADH = +3 ATP = +1 FADH 2 = +1 But there were two molecules of Acetyl CoA that went into the Krebs Cycle… How many would be produced in this case? +6 +2

19. Where is the energy? So far, most of the usable energy from the original glucose molecule is stored in and Where will most of the ATP be made? The Electron Transport Chain NADHFADH 2
