Which accurately describes the function of the electron transport system (ETS)?


A.


It metabolizes pyruvic acid to form ATP, NADH, and FADH2. Both NADH and FADH2 are then used to make four molecules of ADP using electron transfer. The stroma of the cell is the site of this cyclical process.


B.
It takes 6-carbon sugar molecules made during the Krebs cycle and uses them to make ADP. The ETS takes place in the granum of the mitochondria and provides 16 molecules of ADP for every one glucose molecule that enters glycolysis.


C.
It takes electron carrier molecules made during glycolysis and the Krebs cycle and uses them to make ATP. The ETS takes place in the cristae of the mitochondria and provides 34 molecules of ATP for every one glucose molecule that enters glycolysis.


D.
It breaks down a 6-carbon sugar into two 3-carbon pyruvic acid molecules. For each 6-carbon sugar, two molecules of ATP and one molecule of NADH are formed. This process takes place in the thylakoid membrane.

You are familiar with the electron transport system in photosynthesis that takes light energy and converts it to chemical bond energy in the form of ATP and NADPH. This electron transport chain in cellular respiration will take the energy stored in NADH and FADH2 during the Krebs cycle and convert it to chemical bond energy in the form of ATP. In eukaryotes, this reaction takes place on the inner mitochondrial membrane, as is shown in Figure 4.26. Prokaryotes that undergo aerobic respiration also have an electron transport chain located within their plasma membrane, which may be highly folded similar to the inner membrane of the mitochondrion. Thats the answer my friend hope it helps
