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

Answer 1

The first step is breaking down of glucose as a six carbon molecule into a three carbon molecule is called pyruvate may be converted into ethanol and carbon dioxide .this process take place in yeast during fermentation

Answer 2

there r 3 such ways .....

1.absense of oxygen (in yeast )- the glucose which is a 6 carbon molecule is converted into 3 carbon molecule called PYRUVATE ......in cytoplasm......

now this pyruvate is converted into ethanol co2 n energy.....this process is also called as fermentation

2.lack of oxygen(muscle cell)-when the pyruvate is oxidised in this way........lactic acid n low amount of energy is formed.......it is called anaereobic respiration.......

3.presence of oxygen(mitochondria)-when pyruvate is completely oxidised..it forms co2 H2O n energy......it is also called as aerobic way of respiration..........

Answer 3

Glucose can be oxidized through aerobic respiration, which occurs in the presence of oxygen and involves glycolysis followed by the citric acid cycle and oxidative phosphorylation to produce ATP. In the absence of oxygen, glucose can be partially oxidized through anaerobic processes like fermentation, which generate ATP without the use of oxygen but produce lactic acid or ethanol as byproducts.
