1) In the presence of oxygen- When breakdown of glucose is carried out in the presence of oxygen in a cell, it is called as aerobic respiration. Glucose is converted into a 3 carbon molecule called pyruvate which further breaks down in the presence of oxygen to form carbon dioxide and water. Energy is released in this process.

2) (ii)In the presence of oxygen- When breakdown of glucose is carried out in the Absence of oxygen in a cell, it is called as anaerobic respiration.Glucose is converted into a 3 carbon molecule called pyruvate which further breaks down in the absence of oxygen to give lactic acid and ethyl alcohol. This process is called fermentation.
