Study Notes
Metabolic Pathways
- Metabolic pathways have distinct characteristics, including being regulated and often compartmentalized in eukaryotic cells.
Characteristics of Catabolic Pathways
- Catabolic pathways are exergonic systems, generating chemical energy in the form of ATP, GTP, NADH, NADPH, and FADH2 from energy-containing sources.
- Sources of energy include carbohydrates, fats, and proteins.
- End products of catabolic pathways often include carbon dioxide, water, and ammonia.
Examples of Catabolic Pathways
- Glycolysis
- Citric acid cycle (Krebs cycle / cellular respiration)
- Electron transport chain
This quiz covers the main characteristics of metabolic pathways, including their reversibility, types, regulation, and location in eukaryotic cells. It also touches on catabolic pathways and their role in energy production.
