Statement - I :Alpha amino acids exists as zwitterions at pH=7.
Statement - II : The basic amino groups of amino acids excepts proton from the carboxylic group to form a zwitterion.

α-Amino acids are simple molecules that are made of a central C-atom which is bound to a primary amine group NH₂ and to a carboxylic group COOH. In neutral conditions, because of presence of an acidic group (-COOH) and a basic group (-NH₂), it exists as zwitterion because basic group accepts proton from the acidic group.
