Final answer:
True, water is produced during cellular respiration as cells convert glucose and oxygen into carbon dioxide, water, and ATP for energy.
Step-by-step explanation:
Water is indeed a product of cellular respiration. In this crucial process, cells break down glucose in the presence of oxygen to release energy. The entire process can be summarized by the chemical equation: C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy. This equation shows that when one glucose molecule is processed through cellular respiration, it produces six molecules of water, alongside carbon dioxide and energy stored in the form of ATP (adenosine triphosphate).
During cellular respiration, the carbons from glucose are not directly turned into ATP molecules, but instead, they end up as part of carbon dioxide. While ATP synthase does indeed act as both an enzyme and a channel protein, allowing protons to pass through a membrane and synthesizing ATP from ADP and inorganic phosphate.
The stage of aerobic cellular respiration that produces the most ATP is the electron transport chain, where most of the ATP generation happens due to oxidative phosphorylation.
