Detailed explanation-1: -Answer and Explanation: Water is the end products in the electron transport chain in aerobic respiration. The final electron acceptor in the electron transport chain is oxygen, and when electrons combine with oxygen water is produced.

Detailed explanation-2: -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.

Detailed explanation-3: -The end products of the ETC or electron transport chain are the formation of ATP, NAD+, FAD, water, and protons. ETC works as a proton pump since it pumps hydrogen ions or protons through the membrane, and only allows ATP synthase for the formation of ATP.

Detailed explanation-4: -Protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water.
