Cell Respiration
All organisms need energy from food. They obtain this energy through a process called cellular respiration.

Remember ATP!!

THERE ARE 2 TYPES OF RESPIRATION!

Anaerobic Respiration(Fermentation)
Uses NO OXYGEN and produces little energy from glucose – only 2ATP
Starts with the process of GLYCOLYSIS in the CYTOPLASM
C6H12O6 + 2 ATP 2 pyruvic acid + 4 ATP
(start up energy) (3-C Compound) (gain of 2 ATP)

Pyruvic Acid Breakdown in Some Organisms
Break it down into waste products to be excreted
Bacteria/Yeast – break it down into alcohol and CO2
Mammal Muscle Cells – turns into lactic acid
BOTH PROCESSES MAKE 2 ATP in the ABSENCE of OXYGEN

PAUSE FOR A DEMONSTRATION!!

Aerobic Respiration
Requires the presence of Oxygen
Takes place in the mitochondria
COMPLETELY breaks down glucose molecule to generate large amounts of energy (36 ATP)

2 Processes Involved in Aerobic Respiration
Krebs (Citric Acid) Cycle
Electron Transport Chain

Steps:
First, Glycolysis occurs (in the cytoplasm) generating 2 Pyruvic Acids and 2 ATP
Next, Oxygen is used to completely breakdown the pyruvic acid and make CO2 and H2O as wastes and 34 more ATP
As you can see this is MUCH more efficient than anaerobic respiration, WHY?
