TYPES OF CELLULAR RESPIRATION
| Type of Cellular Respiration | Description | Oxygen Requirement | Key Steps/Processes | ATP Yield (per Glucose) |
|---|---|---|---|---|
| Aerobic Respiration | Most common and efficient form of respiration. | Requires Oxygen | 1. Glycolysis 2. Citric Acid Cycle (Krebs Cycle) 3. Electron Transport Chain | Up to 38 ATP |
| Anaerobic Respiration | Occurs in the absence of oxygen or in low-oxygen environments. | Oxygen Not Required | 1. Glycolysis 2. Fermentation (e.g., lactic acid or alcoholic fermentation) | Fewer than 38 ATP |
| Lactic Acid Fermentation | Anaerobic process in which pyruvate is converted to lactic acid. | No Oxygen Required | 1. Glycolysis 2. Lactic Acid Formation | 2 ATP (per glucose) |
| Alcoholic Fermentation | Anaerobic process in which pyruvate is converted to ethanol and CO2. | No Oxygen Required | 1. Glycolysis 2. Ethanol and CO2 Formation | 2 ATP (per glucose) |
