Answer:
Cellular membrane.
Explanation:
In prokaryotes electron transport chain isIn prokaryotes electron transport chain is located in the cell membrane. ETC is defined as the series of complexes which helps in the transfer of electrons from electron donors to electron acceptors via reduction, and oxidation reaction couple the transfer of protons with electron transport across a member.
The primary function of the ETC is generated a transmembrane proton electrochemical gradient, such as oxidation, and reduction reaction.
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities
Protects the plant from losing water. The sharp needles of the tree mean that is has less surface area for the sun to make contact. They may also have differently shaped stomata, in order to prevent water loss
