Respiration

This study guide gives a clear overview of Respiration for Grade 11 Life Sciences. It is designed for quick revision and highlights the key points. Inside, you’ll find: • The difference between breathing and cellular respiration. • The two main types of respiration: • Aerobic respiration – requires oxygen, produces lots of energy (ATP), carbon dioxide, and water. • Anaerobic respiration – no oxygen, produces little energy, and by-products (lactic acid in animals; alcohol + CO₂ in plants/yeast). • The stages of aerobic respiration: glycolysis, Krebs cycle, electron transport chain. • The role of the mitochondria as the “powerhouse” of the cell. • A simple comparison of aerobic vs anaerobic respiration. The notes are kept short and simple so you can easily understand the processes and compare them.
