slide1

Fungus

Characteristics

Most are many celled

Don’t move about

Heterotrophic – Nature’s Recyclers , decomposers

Eukaryotes

Grow best in warm, humid areas

slide2

Why do organisms eat/make food?

  • Create energy in the form of ATP
  • Where does this occur?
  • 3. What process in our cells allows energy to be created?
  • Cellular Respiration
  • C6H12O6+ 6 O26 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 body temperature, some lost as
  • heat
  • * repair, replace cells, or growth
slide3

4. Can energy 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

  • Why???
  • A process called fermentation occurs in the cytoplasm of the cells
  • Producing energy in low amounts when O2levels 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)

Glucose + LOW O2 CO2 + lactic acid + low energy

types Of fungus

sac

Club

Mold

slide5

Fermentation

CO2 + alcohol + energy

Yeast + Sugar + warm, moist environment =

Can we prove this????

  • Make a prediction, will the following substances
  • promote fermentation?
  • Maple syrup
  • Mouthwash
  • Vinegar
  • Honey
  • Bleach
  • Ketchup
  • Salt
slide6

What reactants are needed to start

fermentation?

Sugar

Low amounts of oxygen

Yeast

Warm moist environment

What products are formed?

Carbon Dioxide

Alcohol

Energy
