COOH become deprotonated while NH2 become protonated.

Because at physiologic pH ( ~ pH = 7.4), the carboxyl group is dissociated, forming the negatively charged carboxylate ion(-COO-) and the amino group is protonated(-NH3+).

The amino group gains hydrogen ion that is lost from the carboxyl group.

Because at neutral PH alanine can either act as a base or as an acid.

When the amino acid is placed in a solution at physiologic pH, the carboxyl group loses its hydrogen to the amino group, hence it becomes negatively charged while the amino group gets a positively charged.

Because they are having both the positive and negative charges.
