It depends on how big the feather is.
The useful products is Pyruvate
Glycolysis is a series of reaction that involves the breakdown of glucose to extract energy for cellular respiration. Furthermore, the metabolism of glucose during the process of glycolysis forms a pyruvate with the production of two molecules of ATP. Thus, pyruvate moved into mitochondria and it is used to start citric acid cycle which will yield more energy for the cell.
