Solution
The importance of O2 (oxygen) in aerobic respiration is that it acts as the final electron acceptor at the end of the electron transport chain. During aerobic respiration, electrons are passed along the electron transport chain, with oxygen being the final acceptor. The acceptance of these electrons allows oxygen to then combine with hydrogen ions (H+) to form water. This process is crucial for the production of ATP, the energy currency of the cell.
Oxygen is not mixed with H+ molecules to form water in the formation of ATP, rather it accepts electrons and then combines with H+ to form water.
Oxygen is not released as a by-product in the process of photosynthesis, rather it is consumed. In photosynthesis, plants take in carbon dioxide and release oxygen as a by-product.
