What are the different ways in which glucose is oxidised to provide energy in various organisms?

(N/A) Glucose is first broken down in the cell cytoplasm into a three-carbon molecule called pyruvate. This process is known as glycolysis.
Pyruvate is further broken down by different pathways to provide energy depending on the availability of oxygen:
$1$. In yeast (anaerobic respiration): Pyruvate is converted into ethanol,$CO_2$,and energy.
$2$. In human muscle cells (lack of oxygen): During vigorous exercise,pyruvate is converted into lactic acid and energy.
$3$. In mitochondria (aerobic respiration): Pyruvate is broken down in the presence of oxygen to produce $CO_2$,water,and a large amount of energy.
