Electron transport chain is part of which of the following processes

The electron transport chain is the final and most important step of cellular respiration. While glycolysis and the citric acid cycle produce the necessary precursors, the electron transport chain is where the majority of ATP is created. 

It is a stepwise process of cellular respiration that is responsible for  producing:

1. water (with the help of the oxygen we breath)

2. up to 34 ATP molecules

3. NAD and FAD (which are recycled to be used again in the TCA cycle and glycolysis.)

The electron transport chain takes place in the mitochondria of eukaryotes and  cell membrane of prokaryotes.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
