Aerobic respiration in plants and animals.pptx

For education

1. Anaerobic Respiration Energy production without oxygen

2. Definition Anaerobic respiration is the process of producing energy in cells without using oxygen. It happens when oxygen levels are low or absent.

3. Where It Happens It occurs in the cytoplasm of the cell, not in the mitochondria.

4. Chemical Equation Glucose → Lactic Acid + Energy (in animals) Glucose → Alcohol + Carbon Dioxide + Energy (in plants and yeast)

5. Examples • Muscle cells during intense exercise (produce lactic acid) • Yeast cells during fermentation (produce alcohol and CO₂)

6. Importance of Anaerobic Respiration • Provides energy when oxygen is limited • Helps organisms survive in oxygen-poor environments • Used in making bread, beer, and yogurt
