At the end of the electron transport chain,
|
|
the electrons combine with oxygen and protons to form water
|
|
|
the electrons are used in the formation of ethyl alcohol
|
|
|
the electrons build up inside the mitochondria and diffuse back to a thylakoid
|
|
|
none of the above

Explanation:
Detailed explanation-1: -At the end of the electron transport system, two protons, two electrons, and half of an oxygen molecule combine to form water. Since oxygen is the final electron acceptor, the process is called aerobic respiration.
Detailed explanation-2: -After passing through the electron-transport chain, the “spent” electrons combine with oxygen to form water.
Detailed explanation-3: -The end products of the electron transport chain are water and ATP. A number of intermediate compounds of the citric acid cycle can be diverted into the anabolism of other biochemical molecules, such as nonessential amino acids, sugars, and lipids.
