In the formation of the Zwitter ion, which one of the following donates the proton?
Correct answer: A. COOH
- A. COOH
- B. NH2
- C. CH2COO-
- D. OH-
Explanation
Zwitter ions are ions with two functional groups; they contain both positive and negative charges and are considered neutral. They are also called inner salts. One common example of a zwitter ion is protein, where a proton is transferred from COOH to NH2 but the charge of COO- and NH3 will be balanced internally.

About Macromolecules
Proteins are classified by shape, composition and structure, from primary amino acid sequence to secondary, tertiary and quaternary organisation, and their biological roles are linked to this structure. Enzymes are examined as protein biocatalysts, including active sites, substrate specificity, activation energy, cofactors and factors affecting activity.
