6. Exit Ticket Review
4. DNA is present in both prokaryotic and eukaryotic cells. How is the DNA found in the two types of cells? A. In a prokaryotic cell the DNA is found enclosed by a membrane within the cell and in an eukaryotic cell the DNA is not enclosed by a membrane and is free floating within the cell. B. In a eukaryotic cell the DNA is found enclosed by a membrane within the cell and in an prokaryotic cell the DNA is not enclosed by a membrane and is free floating within the cell. C. In both the prokaryotic and eukaryotic cells the DNA is not enclosed by a membrane and is free floating within the cell. D. In both the prokaryotic and eukaryotic cells the DNA is enclosed by a membrane within the cell.

7. Energy can be stored in chemical compounds which are used by living things as chemical fuel.
Adenosine triphosphate

8. ATP
The main chemical compound that cells use to store and release energy is adenosine triphosphate (ATP).
When the bond between two phosphates (P) is broken, energy is released.

9. ADP is like a partially charged, spent battery.
ATP is like a rechargeable battery.
ADP
ATP
ADP is like a partially charged, spent battery.
ATP is like a fully charged battery that can be used to power reactions in the cell.

10. Cellular respiration and photosynthesis are opposite and connected processes that store and release energy for the cell to use.
products of cell respiration = reactants of photosynthesis
products of photosynthesis = reactants of cell respiration

11. Cellular Respiration Turn and Talk
What would happen if there were no oxygen available to the cell?
Cellular respiration is the process that releases energy by breaking down glucose in the presence of oxygen.
ATP
occurs in the mitochondria (plants and animals)
reactants: oxygen and glucose
products: carbon dioxide, water, and 36 ATP (energy)
C6H12O6 + O2  CO2 + H2O + ATP

12. Photosynthesis Turn and Talk
What would happen if there were no carbon dioxide available for the cell?
Photosynthesis is the process that stores the energy of sunlight in the bonds of glucose, and releases O2.
occurs in the chloroplast (plants only)
reactants: carbon dioxide, water, sunlight
products: glucose, oxygen
sunlight
CO2 + H2O + sunlight  C6H12O6 + O2

13. The process that makes sugar

14. The process that releases oxygen.

15. The process that releases carbon dioxide.

16. The process that requires oxygen to occur.

17. The process that makes ATP

18. Performed in the mitochondria

19. Performed in the chloroplast

20. What are…
the products of cell respiration?

21. What are…
the reactants of cell respiration?

22. What are…
the products of photosynthesis?

23. What are…
the reactants of photosynthesis?

24. But what happens when cells run out of oxygen?
Oxygen is required for cellular respiration to occur.
Respiration is said to be an aerobic process because it requires oxygen.
But what happens when cells run out of oxygen?

25. Fermentation
Fermentation releases energy from food molecules by producing ATP in the absence of oxygen.
Because fermentation occurs without oxygen, it is said to be anaerobic.
Occurs in the cytoplasm of the cell.
Inefficient; produces 2 ATP.

26. Aerobic or Anaerobic?

27. With oxygen

28. Little energy production

29. Mitochondria

30. Yeast

31. Without oxygen

32. Efficient energy production

33. Alcoholic fermentation Lactic acid fermentation
The two main types of fermentation are alcoholic fermentation and lactic acid fermentation.
Fermentation
Alcoholic fermentation
used by yeasts and other microorganisms
forms alcohol and carbon dioxide as waste
Lactic acid fermentation
used by muscles and unicellular organisms
produces lactic acid (why your muscles feel sore after rapid exercise)

34. If anaerobic, state which type of fermentation is occurring.
Aerobic or Anaerobic?
If anaerobic, state which type of fermentation is occurring.

35. A yeast cell produces alcohol

36. Occurs in the cytoplasm of the cell

37. Efficient ATP formation

38. A cheetah sprints toward prey and its muscle cells produce lactic acid

39. The bacteria that cause tetanus can survive in a puncture wound that has healed on the outer surface of the skin

40. Results in the most energy produced

41. Requires the use of a mitochondrion

42. Yeast cells cause bread to rise

43. Occurs in the cytoplasm
