Launch:
HW:

Bullet point regents practice DUE THURSDAY
Castle Learning DUE FRIDAY
Article assignment DUE MONDAY 1/9/17

2. LAUNCH

3. Recall photosynthesis
Brainpop – photosynthesis

4. Cellular Respiration

5. What is Cellular Respiration?
Process that converts the energy stored in glucose into a more usable form (ATP)
Heterotrophs obtain glucose from the foods that we eat.
Autotrophs make glucose through the process of __________________
photosynthesis
Autotrophs and heterotrophs both complete cellular respiration

6. What is ATP? ATP: adenosine triphosphate.
The molecule your cells use for ENERGY.
Energy is released when the third phosphate is broken off the molecule.

8. Now what happens to the glucose?
PHOTOSYNTHESIS  SUGAR STARCH
STARCH  GLUCOSE  CELLULAR RESPIRATION
CELLULAR RESPIRATION  ATP (ENERGY)

9. There are two types of respiration
Aerobic (with oxygen)
Anaerobic (without oxygen)

10. Aerobic Respiration Producing ATP WITH oxygen.
Catalyzed by enzymes in the…
mitochondria.
Efficient form of respiration
1 glucose  36 ATP molecules
The ATP made, in the mitochondria, is used to obtain, transform, and transport materials, and to eliminate wastes.

11. Where does aerobic cellular respiration occur?
In all cells, plant or animal, cellular respiration occurs in the mitochondria.

12. The Equation for cellular respiration
Yes, there is another equation you MUST know…
C6H12O6 + O2  CO2 + H2O +
Glucose + Oxygen - Carbon Dioxide + Water + ATP
Raw materials Products
36 ATP

13. What organelle is this taking place in?
MITOCHONDRIA
Cellular
Respiration
H20
CO2 O2
ATP
C6H12O6

14. Remember what the chloroplasts looked like in comparison to the mitochondria

15. Lab
Is there CO2 in the air we exhale?

16. BRAINPOP Cellular Respiration Photosynthesis
Photosynthesis

17. What if there is no oxygen???

18. Think about it
When you exercise hard, you feel a burning in your muscles. Why do you think that happens????

19. Anaerobic Respiration
WITHOUT oxygen.
Catalyzed by enzymes in the…
cytoplasm.
Inefficient form of respiration
1 glucose  2 ATP molecules only
Poisonous waste chemicals are formed as a result.
Takes place in some bacteria, fungi and yeast.

20. There are 2 types of anaerobic respiration
The Equation
If it occurs in your muscle cells it is…
lactic Acid Fermentation
Lactic Acid is the chemical that builds up in our muscle cells and causes muscle soreness and fatigue. (muscle fatigue)
C6H12O6  CO2 + H2O + lactic acid + 2ATP

21. If it occurs in yeast or bacteria cells it is.. Alcoholic Fermentation
This reaction is how alcoholic beverages are made.
C6H12O6  CO2 + H2O + alcohol + 2ATP

23. So What exactly is ATP used for by organisms
Once ATP is produced, it is stored until the cell needs to use it for work.
What type of work?
Metabolic activity
Removal of waste products
Transport
ATP  Products + energy for metabolism

24. Brain pop Cellular respiration

25. Real Life Connections What do pickles, bread yogurt, wine, beer, and cheese have in common?
All of these foods are made by fermentation.
When you ferment a food, you encourage growth of “good” microorganisms in it, while preventing growth of spoilage-causing microorganisms.
Doing this successfully may require controlled conditions, such as temperature and pH.
By eating spoilage-sensitive parts of the food, and releasing chemicals as a by-product, the microorganisms help preserve the food, and change its flavor and texture in interesting ways.

26. Here is a brief look at how fermentation is used to make different foods:
Pickled Vegetables.
The vegetable is soaked in a salt brine, allowing the growth of bacteria that eat the vegetable’s sugars and produce tart-tasting lactic acid.
Wines.
Yeasts, added to crushed grapes eat the grapes’ sugar and produce alcohol.

27. Breads
Yeasts, added to dough, digest sugars (derived from starches in dough) and produce carbon dioxide causing the dough to rise.
Cheeses
Milk bacteria digest the milk sugar lactose and produce lactic acid, which acts with the added enzyme rennet to curdle the milk. The cheesemaker drains off the whey and compacts the curds, which various microbes then ripen into a mature cheese.

29. CHLOROPLASTS VS. MITOCHONDRIA
