Answer:
C. Thylakoid membranes of chloroplasts.
Explanation:
The thylakoid membrane is the site of two distinct varieties of electron transport that are utilized during photosynthesis, i.e
Noncyclic electron transport( which produces NADPH + H+ and ATP).
Cyclic electron transport (which delivers just ATP).
The ETC is the biochemical pathway that is formed of protein complexes and results in ATP formation. Molecules of ETC are found in the thylakoid membranes of chloroplasts.
What is ETC?
ETC or the electron transport chain is the biochemical transfer of the electrons from one complex to another through the redox reactions and of the protons across the membrane.
In the thylakoid membranes of chloroplasts two different electron transportation occurs, noncyclic electron transport and cyclic electron transport, they deliver the ATP, NADPH+, H+ and just ATP respectively.
Therefore, the molecules of ETC are found in the option c. thylakoid membrane of the chloroplast.
