1. Wake-up Briefly explain what happens in Anaerobic respiration.
What organisms undergo anaerobic respiration?
What does anaerobic mean?

2. Wake-up Pyruvate is “handled” differently depending on the organism.
a. What happens to pyruvate in simple organisms?
b. What happens to pyruvate in complex organisms?
2. What does anaerobic mean?

3. Cellular Respiration II: Aerobic Respiration

4. Purpose of Cell Respiration
The process in which glucose (food) is broken down into ATP (usable energy)
ATP
C6H12O6

5. Cell Respiration Summative Equation (Formula)
C6H12O6 + O2
CO2
H2O
ATP + +

6. Glycolysis (Simple): Result
Glucose is broken down into pyruvate and ATP. The ATP made is enough energy so pyruvate is broken down in ANAEROBIC RESPIRATION through fermentation.

9. Glycolysis (Complex)
Glucose is broken down into pyruvate and ATP. The pyruvate is then moved to the mitochondria for AEROBIC RESPIRATION to make more ATP.
