Question

10 cbse show the experiment in which carbondioxide is given out during respiration

Answer 1

Aerobic respiration – In this type of respiration oxygen is utilised. As a result, complete oxidation of glucose takes place and maximum amount of energy is released. This type of respiration can be represented by the following equation:

Aerobic respiration involves three stages-Glycolysis, Krebs cycle and ETS. All the events associated with glycolysis occur in cytoplasm and events associated with Kreb cycle and ETS take place in mitochondria.

Anaerobic respiration – In this type of respiration food is oxidised in the absence of oxygen. In this case, incomplete oxidation of glucose results in release of lesser amount of energy. The process of anaerobic respiration can be represented by the following equations:
