Which reaction involves the removal of electrons from a molecule?

Which reaction involves the removal of electrons from a molecule?

• A. Oxidation
• B. Reduction
• C. Hydrolysis
• D. Phosphorylation

Answer: (D)

Removing electrons from a molecule is oxidation, a redox process where the oxidation state increases as electrons are lost. Oxidation always pairs with reduction, where another substance gains those electrons. Hydrolysis breaks bonds using water and doesn’t involve electron transfer. Phosphorylation adds a phosphate group to a molecule, changing its structure and charge but not by removing electrons. So the concept described is oxidation.
