Question

Why does hydrogen bond so tightly to oxygen during cellular respiration ? (1 point) is not electronegative , but oxygen is is less electronegative than oxygen . is more electronegative than oxygen It is electronegative , but oxygen is not.

Answer 1

The correct reason for why hydrogen bonds tightly to oxygen during cellular respiration is that **oxygen is more electronegative than hydrogen**. This means that oxygen has a stronger attraction for electrons compared to hydrogen, leading to the formation of polar covalent bonds in molecules like water (H2O). This polarity contributes to the strong hydrogen bonds formed between water molecules and between water and other molecules in biological systems, playing a crucial role in cellular respiration and other biochemical processes.
