When oxygen accepts electrons, water is produced as a by-product.Group startsTrue or FalseTrue, unselectedFalse, unselected

Understanding the Statement

The statement mentions that when oxygen accepts electrons, water is produced as a by-product. To analyze this, we can refer to the basic principles of redox reactions in which oxygen acts as an electron acceptor.

Analysis of the Reaction

1. Redox Reaction: In many biochemical processes, especially during cellular respiration, oxygen acts as the final electron acceptor. During this process, oxygen combines with hydrogen ions (protons) and electrons to form water (H₂O).

   $\text{O}_2 + 4\text{e}^- + 4\text{H}^+ \rightarrow 2\text{H}_2\text{O}$

2. Formation of Water: Thus, the acceptance of electrons by oxygen indeed produces water as a by-product. This is a common occurrence during aerobic respiration in cells.

Conclusion

Based on the analysis, the statement is True: when oxygen accepts electrons, water is indeed produced as a by-product.
