Aerobic Respiration

A metabolic process that occurs in the presence of oxygen and is essential for plant growth with the conversion of glucose (produced by photosynthesis), via glycolysis, into pyruvic acid. These pyruvate molecules are then transported into the mitochondria as part of the Kerbs cycle (also called the citric acid cycle) resulting in energy (ATP molecules) released for plant growth, as well as carbon dioxide and water vapour being released to the atmosphere.

The energy molecules are also used in various biochemical pathways, including the synthesis of proteins, nucleic acids, photosynthesis, active transport of hydrogen and nutrient ions across cell membranes, and cell division. This all emphasises the importance of having a well aerated medium, whether as surface air flow a well aerated (oxygenated) rootzone, with good root depth and mass. This improves the efficiency of plant respiration, and photosynthesis, as well as improves the soil ecosystem, all contributing to a more resilient plant.
