1. Why do organisms eat/make food? Create energy in the form of ATP
2. Where does this occur? mitochondria
3. What process in our cells allows energy to be created? Cellular Respiration
C6H12O6 + 6 O2 6 CO2 + 6 H2O + Energy glucose ATP Let’s Prove it!!! Bromthymol Blue[base] turns green [neutral] then yellow[acid] proving C02 is present 4.What happens to energy produced in cell respiration? * used to maintain constant body temperature, some lost as heat * repair, replace cells, or growth

Why???
A process called fermentation occurs in the cytoplasm of the cells
Producing energy in LOW amounts when O2 levels are low.
*Yeast [dehydrated, but not dead] is a Fungus that allows fermentation to occur
• Yeast naturally found in soil or on plants (see article)
5. Can energy(ATP) be produced when oxygen(O2) levels are low?
Hint: What happens when you run long distances or run for a long period of time? How do you feel? Yes, but O2 being used faster than produced- body also making lactic acid – causing muscles to ache, burn, feel sore
Glucose + LOW O2 CO2 + lactic acid + LOW ATP energy

• Cellular Respiration occurs in ALL cells and can take place either with or without oxygen present.

Fermentation: occurs when no or low oxygen is available to the cell (2 kinds: Alcoholic and Lactic Acid)• Also called anerobic respiration• Much less ATP produced than in aerobic respiration

FERMENTATION
Yeast + Sugar + warm, moist environment = CO2 + alcohol + energy
Make a prediction, will the following substances promote fermentation?
1. Maple syrup 2. Mouthwash3. Vinegar4. Honey5. Bleach6. Ketchup7. Salt
Can we prove this????

What reactants are needed to startfermentation?
SugarLow amounts of oxygenYeastWarm moist environment
What products are formed?Carbon Dioxide AlcoholEnergy

• Alcoholic fermentation—occurs in bacteria and yeast
Process used in the baking and brewing industry—yeast produces CO2 gas during fermentation to make dough rise and give bread its holes
glucose ethyl alcohol + carbon dioxide + 2 ATP

• Lactic acid fermentation—occurs in muscle cells
Lactic acid is produced in the muscles during rapid exercise when the body cannot supply enough oxygen to the tissues—causes burning sensation in muscles
glucose lactic acid + carbon dioxide + 2 ATP
