Study Notes
Cellular Respiration Overview
- Begins with glucose, the primary energy source for cellular processes.
- Involves multiple stages, including glycolysis, the citric acid cycle, and the electron transport chain.
Glycolysis
- Occurs in the cytoplasm of the cell.
- Breaks down glucose to produce 2 pyruvic acids.
- Results in a net gain of 2 ATP molecules.
- Can function under both aerobic and anaerobic conditions.
Anaerobic Processes
- An example is fermentation, which occurs when oxygen is not available.
- Fermentation converts pyruvic acid into lactic acid, resulting from anaerobic respiration.
Aerobic Respiration
- Begins with the citric acid cycle, which utilizes acetyl CoA.
- Takes place in the mitochondria, the powerhouse of the cell.
- Produces a net yield of 2 ATP, along with 6 NADH and 2 FADH2 molecules.
- Releases 2 CO2 molecules as waste products.
Electron Transport Chain
- The products of the citric acid cycle are utilized here.
- Situated in the mitochondria and responsible for generating a significant amount of ATP, approximately 34 ATP molecules.
