[autotrophs]

3. 8.3 DATA ANALYSIS
1-ANALYZE how did the virus affect lactic acid production in the cells?
-virus increased lactic acid production after 4 hours

4. 8.3 DATA ANALYSIS
2- CALCULATE After 8 hours what percentage was the lactic acid higher in the virus group than in the control group?
By what percentage was ATP production decreased?
-lactic acid increased ~75%
[7 - 4=3 : 3/4 = .75]
-ATP production decreased ~28%
[7 – 5 = 2 : 2/7 = .28]

13. ANAEROBIC RESPIRATION-NO O2 
CAUSE:
CELLS CAN’T GET ENOUGH OXYGEN
FERMENTATION FOLLOWS:
GLYCOLYSIS
IT REPLACES:
KREB’S CYCLE AND
ELECTRON TRANSPORT
FERMENTATION IS NEEDED TO
REPLENISH SUPPLY OF NAD+ FOR GLYCOLYSIS
2 ATP

14. STEP 1-GLYCOLYSIS breaks down glucose cytoplasm
anaerobic - NO O2 needed
needs 2 ATP molecules to start
EACH GLUCOSE MOLECULE NETS:
2 ATP molecules
2 NADH
2 molecules of pyruvate

15. STEP 2-KREB’S CYCLE breaks down pyruvate -- forms CO2
mitochondria of cell
aerobic - requires O2
EACH MOLECULE GLUCOSE PRODUCES:
2 ATP
8 NADH
4 CO2

16. STEP 3-ELECTRON TRANSPORT
ATP made from high-energy electrons & protons
mitochondrial membrane
aerobic - requires O2
EACH GLUCOSE MOLECULE PRODUCES:
32 ATP
electrons & protons w/O2  make H2O

17. ANAEROBIC RESPIRATION-FERMENTATION NO O2 present--
LACTIC ACID FERMENTATION
-produced in muscles during strenuous exercise-not enough O2
-lactic acid produced by many microorganisms
-used in making yogurt, sour cream, cheese
ALCOHOL FERMENTATION
-used in making
beer & wine
-occurs in organisms such as bacteria/yeast
