Anaerobic Respiration: Observing Yeast's Oxygen-Free Energy Production

The video explains anaerobic respiration, focusing on how organisms like yeast obtain energy from glucose without oxygen. It demonstrates an experiment using yeast, glucose, vegetable oil, and lime water to show yeast's anaerobic respiration. The setup involves mixing yeast with glucose and sealing it with oil to prevent oxygen entry. Observations after 40 minutes reveal carbon dioxide production, turning lime water cloudy. The video also discusses the chemical reactions involved and the applications of anaerobic respiration in food production, such as cheese and yogurt making.
