What is ATP?

1. How does energy get converted from food molecules to muscles? ________________________________

2. According to the webpage, the analogy for ATP is that ATP works like a rechargeable _________________.

3. Click on the arrow to the next page. Pull apart the ice cream. What happens when food is broken down in the body? ________________________________________________________

4. Pull a Phosphate from the recharged ATP, what happened? ________________________________________

What is Photosynthesis?

5. Where on the plant does photosynthesis take place? ____________________________

6. The energy from the sun enters into what organelle in the plant? ____________________________

7. How does the plant get water for photosynthesis? ____________________________

8. What gas enters the plant for photosynthesis? ____________________________

9. Where does it enter the plant? ____________________________

10. What gas exits the plant during photosynthesis? ____________________________

11. Where does it exit the plant? ____________________________

12. What is the overall equation for photosynthesis? ____________________________

The Light reaction of Photosynthesis:

13. What is split to replenish the electrons (that also makes Oxygen gas)? ____________________________

14. The excited electrons pump what ion to create a gradient? ____________________________

15. The ATP synthase uses this gradient to restore ADP back to ATP. ____________________________

What is this process called?

The Dark reaction of Photosynthesis:

16. Which of the following statements is true about the Calvin cycle?

[pic]AIt requires the presence of sunlight

[pic]BIt happens in the stroma of a chloroplast

[pic]CIt can happen if it has enough ATP even if no NADPH is available

[pic]DAll of the above

17. How many repeats of the Calvin cycle are needed to make one glucose molecule?

[pic]A1

[pic]B3

[pic]C6

[pic]D9

18. Cycles are beneficial in living systems because:

[pic]AThey are efficient

[pic]BThey allow repeated use of limited resources

[pic]CThey save energy

[pic]DAll of the above

19. The Calvin cycle is the second part of the photosynthesis reaction. Photosynthesis stores energy from the sun as well we carbon from the air together in the high-energy molecule, glucose. Does the Calvin cycle itself have a use or release energy? With energy that is used, where does it come from?

21. What molecule enters Glycolysis?

22. What gas is released during the Krebs Cycle?

23. What molecules are released from the Krebs cycle and enter the Electron transport chain?

24. What energy molecule is restored as a product of cellular respiration?

What is Glycolysis?

25. What is the main reactant for glycolysis? _____________________________________________

26. What is the product of glycolysis? __________________________________________________

27. How many ATP molecules are used to start glycolysis? ___________

28. What are the 3 carbon molecules called? _________________________________________________________ What molecule is required for aerobic conditions? (Not on slide, think!) _________________________________

29. What happens if there are anaerobic conditions, what is pyruvate converted into? __________________________

(Aka the source of sore muscles!)

Alcoholic Fermentation in Yeast:

In this animation, use the enzymes to convert glucose into ATP.

30. When you add the fifth enzyme (dark purple) to pyruvate, what did you have to add? _______________________________

31. When you added the sixth enzyme to pyruvate with Phosphate and ADP, what did it make? _________________________

32. When you add the final enzyme, what were the products of the reaction? _____________________________________
