1. Cellular Respiration

3. Cellular Respiration: The Big Picture
Cellular Respiration - process by which all organisms break down organic compounds and receive energy. Breakdown of organic compounds into ATP
Cellular Respiration: The Big Picture
C6H12O O > 6CO H2O ATP
Glucose + Oxygen > Carbon Dioxide + Water + ATP
Reverse of Photosynthesis

4. Glycolysis - First step in cellular respiration
If oxygen is absent then Fermentation will take place
If oxygen is present Aerobic Respiration will take place
Glycolysis produces two molecules of pyruvic acid and ATP

5. Fermentation - Cellular respiration without the need of oxygen
Lactic Acid Fermentation - causes pain in muscles (Animals)
Alcoholic Fermentation - Bread and Wine Making (Ethyl Alcohol from Yeasts)
Animal Cells
Yeasts

7. Aerobic Respiration occurs in the mitochondria and is
very efficient at producing ATP
Steps to Aerobic Respiration:
1)Glycolysis occurs in Cytoplasm and turns glucose into pyruvic acid
Pyruvic acid is changed into acetyl coenzyme A (Acetyl CoA)
Acetyl CoA enters the…..
2)Krebs Cycle produces CO2 and ATP
Electrons produced in Krebs cycle are passed down the 3)Electron Transport Chain
Oxygen is the final electron acceptor and forms water
Total energy produced from one molecule of glucose = 38 ATP (Maximum)
