1. 9.2 The Process of Cellular Respiration

2. Q: What happened during the process of glycolysis?
A: During glycolysis, 1 molecule of glucose, a 6-carbon compound, is transformed into 2 molecules of pyruvic acid, a 3-carbon compound.
NAD+- Electron carrier involved in glycolysis.

3. Glycolysis Glucose broken down 2 ATP produced NADH produced
No O2 required
Happen in cytoplasm

4. Q: What happened during the Krebs cycle?
A: During the Krebs cycle, pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions.
Matrix-the innermost compartment of the mitochondrion & site of Krebs cycle reactions.
2 steps- Citric Acid Production & Energy Extraction.

5. The Krebs Cycle
Pyruvic acid is broken down into CO2 which produces Citric Acid.
Energy is used
Happens in mitochondria
2 ATP produced

6. Q: How does the electron transport chain use high-energy electrons from glycolysis and the Krebs cycle?
A: The electron transport chain uses the high-energy electrons from glycolysis and the Krebs cycle to convert ADP into ATP.

7. Electron Transport & ATP Synthesis
Transports electrons
Converts ADP into ATP
32 ATP produced
Total in CR=36ATP

8. Q: How much ATP does cellular respiration generate?
6O2 + C6H12O energy+6CO2 + 6H2O
Q: How much ATP does cellular respiration generate?
A: Together, glycolysis, the Krebs cycle, and the electron transport chain releases about 36 molecules of ATP per molecule of glucose. 2 2 32
