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
