II. How Does a Cell Obtain Energy From “Food?”
18
Cellular Respiration + + + 6 O2 6 H2O 36 ATP C6H12O6 6 CO2 oxygen
water energy! + 36 ATP C6H12O6 glucose 6 CO2 carbon dioxide
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

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 Starts here
36
Cell Cycle
37
Cell division Cytokinesis (cell splits)
4 Stages of Mitosis (chromosomes separate) Prophase Metaphase Anaphase Telophase Cytokinesis (cell splits)
38
telophase anaphase metaphase Stages of Mitosis cytokinesis early
prophase late prophase anaphase metaphase
39
Where should you look in an organism to find mitosis?
