Describe the mechanism of Respiration.
Mechanism of respiration – Glucose molecule is broken down into an intermediate molecule, Pyruvic acid. Breakdown of Pyruvic Acid in Anaerobic Respiration – In this process in absence of oxygen, the pyruvic acid is incompletely reduced to ethyl alcohol. Glucose → Ethyl alcohol + CO2+2 ATPGlucose → Ethyl alcohol + CO2+2 ATP Breakdown of Pyruvic Acid in Aerobic Respiration – In this process the pyruvic acid is completely oxidized into CO2 and H2O is the presence of oxygen. This process occurs in the mitochondria of the cell and is known as Kreb’s cycle.
