What is common between aerobic and anaerobic respiration?
Answers
Cellular respiration is the
process by which glucose is broken down to form ATP molecules, which act as
carriers of cellular energy. The first phase is called glycolysis and is common
to both aerobic (respiration in the presence of oxygen) and anaerobic (respiration
in the absence of oxygen) respiration. During glycolysis, glucose is split to
forms two pyruvate molecules and 2 molecules of ATP. This occurs in the
cytoplasm of the cell. If oxygen in present, the pyruvate molecules will be
used in the Krebs cycle, to yield more ATP molecules. If oxygen is absent, the
pyruvate is converted into lactic acid, or ethanol and carbon dioxide, in
animals or plants, respectively.
■ Anaerobic respiration
♤ 1. This process take place in absence of oxygen.
♤ 2. Incomplete breakdown of glucose take place.
♤ 3. End products are Ethanol, Carbon dioxide and Energy.
♤ 4. It occurs in yeast and sometimes in muscle cell of human being.
♤ 5. Less amount of energy is released during this process.
