1. CELLULAR RESPIRATION

2. In the last chapter green plants used ________________ to
AUTOTROPHS
___________ use energy from sunlight or chemicals to make their own food
In the last chapter green plants
used ________________ to
trap energy from __________
and make ______________
PHOTOSYNTHESIS
sunlight
food (glucose)

3. PHOTOSYNTHESIS CELLULAR RESPIRATION
Quick Overview Video
PHOTOSYNTHESIS
___________ + _________ + ___________ →_______________ + __________
6 CO2
6 H2O
C6H12O6
6O2
CELLULAR RESPIRATION
C6H12O6
6 CO2
_____________ + _________ →________ + __________ + __________
6O2
6 H2O
The two equations are exact opposites!

4. Why do cells need cellular respiration?
Recall…Energy stored in glucose cannot be used by the cell
Cellular Respiration releases energy in glucose and converts it to ATP, the form of energy that the cell CAN use

5. What kind of organisms do this?
animals
plants
bacteria
fungi
ALL ORGANISMS, INCLUDING BACTERIA USE CELLULAR RESPIRATION TO MAKE ATP!

6. TWO TYPES OF CELLULAR RESPIRATION
Aerobic Respiration
Anaerobic Respiration

7. Aerobic Cellular Respiration (WITH Oxygen)
Occurs in the mitochondria
Reactants (requires): Glucose (C6H12O6) & Oxygen (O2)
Products (makes): Carbon dioxide (CO2) & Water (H2O) & 32 ATP (that’s A LOT!!)

8. This is the carbon dioxide that you breathe out when you exhale!!!

9. Anaerobic Respiration: (WITHOUT Oxygen)
Occurs in the cytoplasm
Two steps: glycolysis followed by fermentation
But only makes 2 ATP (That’s a little !!)

10. Two types of anaerobic respiration (fermentation)

11. 1) Lactic Acid Fermentation
Occurs in muscle cells of animals (& humans)
When you exercise and can’t take in oxygen as fast as your muscles need, then your muscle cells produce lactic acid (makes your muscles sore!)

12. 2) Alcohol Fermentation
Occurs in yeast and some bacteria
Produce alcohol & CO2 when they perform fermentation
Causes bread to rise and used to make alcoholic beverages
