19. A) Aerobic respiration - the process that releases energy (ATP) by breaking down glucose, in the presence of oxygen

20. occurs at rest, or

21. when you are bringing it! 

22. electron transport chain
occurs along the cristae of the mitochondria
two stages:
Kreb’s cycle
electron transport chain

24. Cellular Respiration Starts with . . .

25. B) Anaerobic respiration -produces ATP by breaking down glucose without oxygen

26. lactic acid fermentation (e. g
lactic acid fermentation (e.g. sore muscles, yogurt, cheese, pickles, kimchi)

27. Energy Tally Anaerobic = 2 ATP Aerobic respiration Glycolysis 2 ATP
Kreb’s cycle ATP
Electron Transport ATP
+36 ATP

28. III. What Are the Stages in the Life of a Cell?

29. Cell Cycle

30. G1 cell growth
S DNA replicates
G2 preparation for cell division

31. DNA (genetic instructions)
A Typical Cell
cell membrane
nucleus
(w/ nuclear membrane)
DNA (genetic instructions)

32. during G1
DNA is in chromatin form (“loose” threads)

33. before cell division

34. DNA is replicated and forms chromosomes
before cell division
DNA is replicated and forms chromosomes

35. Cell Cycle

37. Cell division Cytokinesis (cell splits)
4 Stages of Mitosis (chromosomes separate)
Prophase
Metaphase
Anaphase
Telophase
