Cellular Respiration

DaShario GilliamLRC 320

Cellular Respiration • Both requires and sends off energy: Aerobic

and Anaerobic • 3 Phases 1. Glycolysis 2. Citric Acid cycle 3. Electron Transport Chain C6H12O6+6O2->6 CO2 +6H2O + Energy (ATP + Heat)

Glycolysis

• Is splitting Glucose (sugars) molecules into two Pyruvate molecules

• Occurs in the Cytoplasm • Creates and requires ATP molecules • Can occur with or without oxygen Ex. When a human eats a pie the sugar molecules convert to glucose molecules that are then used as pyruvate molecules to prepare for the Citric Acid Cycle

Glycolysis

• Formula (C6H12O6)• Glucose 6 Carbons…….breaks into 2 sets of 3

Carbons which converts into pyruvate molecules

• Uses 2 ATPs, 2NAD (H+) converts to 2NADH• http://www.khanacademy.org/science/biology/cellul

Citric Acid Cycle

• Requires oxygen for the cycle to process pyruvates and complete the oxidation of glucose

Electron Transport Chain

• NADH passes the electrons through the Electron Transport Chain

• Produces the most ATP as the end product; which is used as energy

Conclusion

• Summary Cellular Respiration is a biological process that consumes energy in the form of Glucose and produces it as APT. The process consists of three steps: 1. Glycolysis 2. Citric Acid Cycle 3. Electron Transport Chain
