Study Notes
Stages of Aerobic Cellular Respiration
- Four primary stages: Glycolysis, Acetyl-CoA Formation, Citric Acid Cycle, Electron Transport
- Glycolysis converts glucose into pyruvic acid; occurs in the cytoplasm
- Acetyl-CoA Formation converts pyruvic acid with coenzyme A into Acetyl-CoA; occurs in mitochondria
- Citric Acid Cycle utilizes Acetyl-CoA to produce energy-rich compounds; takes place in the mitochondrial matrix
- Electron Transport Chain uses NADH and FADH2 to generate ATP; located in the inner mitochondrial membrane
Starting Molecules
- Glycolysis begins with glucose as the main substrate
- Acetyl-CoA Formation starts with pyruvic acid and coenzyme A
- Citric Acid Cycle starts with Acetyl-CoA
- Electron Transport utilizes NADH and FADH2
Products of Each Stage
- Other byproducts of aerobic respiration include enzymes and carbon dioxide (CO2)
Location of Stages within the Cell
- Glycolysis occurs in the cytoplasm where glucose becomes pyruvic acid
- Acetyl-CoA Formation and Citric Acid Cycle occur in mitochondria, with the former in the mitochondrial matrix
- Electron Transport is conducted in the inner membrane of mitochondria
Types of Cells Involved
- Glycolysis can occur in both prokaryotic and eukaryotic cells
- Citric Acid Cycle and Electron Transport are specific to eukaryotic cells
- Acetyl-CoA Formation can occur in anaerobic conditions, while electron transport is exclusive to aerobic cells
