Final answer:
Oxygen combines with hydrogen ions and electrons to form water as a waste product during cellular respiration
Step-by-step explanation:
Oxygen combines with the leftover hydrogen ions and the electrons to form water as a waste product. This statement is True. In biological systems, oxygen combines with hydrogen ions (H+) and electrons to form water during the electron transport chain in cellular respiration. This process occurs in the mitochondria and is important for generating ATP, the energy currency of cells.
