Protons fall down their concentration gradient through the ATP-synthase and are picked up by oxygen, along with electrons, to make water. So, ATP and water " comes out " the electron transport chain.

Water is a waste product of the electron transport chain. During the final step of electron transport, oxygen is reduced to form water as a byproduct.
During cellular respiration, cells utilize oxygen to produce energy in the form of ATP, and release carbon dioxide as a byproduct. Oxygen is necessary for the final electron acceptor in the electron transport chain, while carbon dioxide is a waste product produced during the citric acid cycle. This process occurs in all aerobic organisms to sustain life.
Oxygen is removed from the molecule in 2B to generate energy through a process called cellular respiration. This reaction involves breaking down the molecule to release energy stored in its chemical bonds. Oxygen acts as the final electron acceptor in the electron transport chain, facilitating the production of ATP, the cell's main energy currency.
The main raw materials used in cellular respiration are glucose (from carbohydrates) and oxygen. Glucose is broken down in a series of chemical reactions to produce energy in the form of ATP, which is used to fuel cellular processes. Oxygen is used as the final electron acceptor in the electron transport chain to complete the process of generating ATP.
Oxygen is necessary as the final electron acceptor in aerobic respiration because it has a high electron affinity, allowing it to efficiently accept electrons and complete the electron transport chain. This process generates a large amount of energy in the form of ATP. Without oxygen, the electron transport chain would not function properly, leading to a decrease in ATP production and ultimately cell death.
Carbon dioxide is the waste product exhaled from the lungs during respiration.
