Cellular Respiration
the process of breaking down carbohydrates (food) to make energy (ATP
glucose is broken down to make 2 pyruvic acids, and 2 ATP
Aerobic Respiration
-Making ATP in the presence of Oxygen
-makes 38 ATP per 1 glucose molecule
Anaerobic Respiration
-Making ATP with out oxygen present
-makes 2 ATP per 1 glucose molecule
Lactic Acid Fermentation
-Done when our body is using more oxygen than we can breathe in
-The pyruvic acid made in glycolysis is turned into lactic acid and NAD+ is also made
-This allows glycolysis to continue
Alcoholic Fermentation
-Yeast turn pyruvic acid into ethyl alcohol and NAD+
-This allows glycolysis to continue, and makes all the ATP that yeast need
Krebs Cycle
-Done only when enough oxygen is available
-turns the pyruvic acid from glycolysis into a variety of compounds
-releases 2 CO2 molecules for every pyruvic acid used
-Also makes NADH and FADH2 to be used in the electron transport chain
Energy carrying molecules made in the Krebs cycle
Electron Transport chain
-takes place in the inner membrane of the mitochondria
-uses NADH and FADH2 to gain excited electrons to make ATP
- Oxygen must be present to accept the used electrons at the end of the process
Overall reaction for cellular respiration
sugar + O2 ---> CO2 + H2O + Energy
