Study Notes
Respiration
- Respiration is a crucial process for releasing energy from glucose (a sugar)
- This energy powers many cellular functions
- Respiration occurs in every living cell.
Aerobic Respiration
- Requires oxygen
- Occurs in mitochondria
- Glucose + Oxygen → Carbon Dioxide + Water + Energy
- More efficient than anaerobic respiration, releasing more energy
Anaerobic Respiration
- Does not require oxygen
- Less efficient than aerobic respiration, producing less energy
- Different products in different organisms
- In humans: glucose → lactic acid + energy (lactic acid buildup can cause pain)
- In microorganisms (e.g., yeast): glucose → carbon dioxide + ethanol + energy (process called fermentation, used to make beer)
