1. 1.Most are multicellular 2.Eukaryotes- have a nucleus, some more than one 3.Heterotrophic – Nature’s Recyclers, decomposers 4.Don’t move about 5.Grow best in warm, humid areas

3. 1.Why do organisms eat/make food? Create energy in the form of ATP 2.Where does this occur? 3. What process in our cells allows energy to be created? Cellular Respiration C 6 H 12 O 6 + 6 O 2 6 CO 2 + 6 H 2 O + Energy glucose ATP Let’s Prove it!!! Bromthymol Blue[base] turns green [neutral] then yellow[acid] proving C0 2 is present 4.What happens to energy produced in cell respiration? * used to maintain body temperature, some lost as heat * repair, replace cells, or growth

4. Why???  A process called fermentation occurs in the cytoplasm of the cells  Producing energy in low amounts when O 2 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) 4. Can energy be produced when oxygen(O 2 ) 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 O 2 being used faster than produced- body also making lactic acid – causing muscles to ache, burn, feel sore Glucose + LOW O 2 CO 2 + lactic acid + low energy

5. Yeast + Sugar + warm, moist environment =CO2 + alcohol + energy Make a prediction, will the following substances promote fermentation? 1.Maple syrup 2.Mouthwash 3.Vinegar 4.Honey 5.Bleach 6.Ketchup 7.Salt Can we prove this????

6. Sugar Low amounts of oxygen Yeast Warm moist environment Carbon Dioxide Alcohol Energy
