1. Yeast is Beast!

2. - The Marathon -
If somebody challenged you to a run a race, how should you prepare to win?
Practice
Eat the right foods
Drink the right liquids

3. All living organisms break down sugars to get energy
All living organisms break down sugars to get energy. In humans this breakdown usually occurs with oxygen.

4. To understand how Aerobic and Anaerobic Respiration Occurs
Aim:
To understand how Aerobic and Anaerobic Respiration Occurs

5. SWBAT: Learn how the type of sugar affects the rate of respiration.
Learn how the concentration of sugar affects the amount of energy produced.
Determine the rate of respiration while using yeast to breakdown different sugars.

6. What is Aerobic Respiration?
The breaking down of sugar to produce energy where oxygen is present.
Glucose + Oxygen  Carbon Dioxide + Water+ Energy

7. When We Exercise…
After two minutes of exercise, the body responds by supplying working muscles with oxygen.
When oxygen is present, glucose can be completely broken down into carbon dioxide and water

8. It is also known As Fermentation Yeast goes through Fermentation
Anaerobic Respiration refers to the oxidation of molecules in the absence of oxygen to produce energy
It is also known
As Fermentation
Yeast goes through Fermentation

9. Chemical Formula for Anaerobic Respiration
Energy + Glucose
Ethanol + Carbon Dioxide + Energy

10. What is Yeast? Yeast are single-celled fungi A living organism
Related to the other fungi including:
edible mushrooms
common baker's yeast used to leaven bread
molds that ripen blue cheese; molds that produce antibiotics

11. How does yeast use energy ?
Yeast cells digest food to obtain energy for growth (heterotroph)
Their favorite food is sugar
sucrose (beet or cane sugar),
fructose and glucose (found in honey, molasses, maple syrup and fruit)
maltose (derived from starch in flour).

12. Lab Experiment
We will be testing different solutions to see which will give us the most energy
