Study Notes
Respiration
- Breaks down sugars to release energy in the absence of oxygen
- Typically slower and less efficient than aerobic respiration
- Involves chemicals other than oxygen and carbon dioxide
Classification of Organisms Based on Respiration
- Facultative Anaerobes: can perform either aerobic or anaerobic respiration depending on oxygen content
- Example: Coliform bacteria
- Microaerophiles: break down sugars in the presence of minute amounts of oxygen to produce energy
Classification of Organisms Based on Environment
Temperature
- Mesophiles: require moderate temperatures to survive
- Extremophiles: can survive in extreme conditions
- Thermophiles: can resist high temperatures
pH Levels
- Neutrophiles: require moderate conditions to survive
- Acidophiles: can tolerate low pH conditions
- Alkaliphiles: can tolerate high pH conditions
