Question

cellular respiration quick check
why does hydrogen bond so tightly to oxygen during cellular respiration? (1 point)

• it is less electronegative than oxygen
• it is not electronegative, but oxygen is
• it is more electronegative than oxygen
• it is electronegative, but oxygen is not

Explanation:

Electronegativity is the ability of an atom to attract shared electrons in a bond. Oxygen has a much higher electronegativity than hydrogen. This difference means oxygen pulls the shared electrons in the O-H bond closer to itself, creating a strong polar covalent bond between hydrogen and oxygen.

Answer:

A. It is less electronegative than oxygen
