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.

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.

answer; ///(b) it is composed of four protein chains and four heme groups;
