When two amino acids are joined together to form a peptide bond there is a net … (1 point) loss of one water molecule gain of one water molecule loss of one amino group gain of one carboxyl group?

A peptide bond is a form of covalent bond that is formed when the carboxyl terminal of an amino acid condense with the amino terminal of another amino acid. In this process, one water molecule is lost (see attached image). There will be no gain of water as this reaction is not a hydration reaction. Amino and carboxyl groups are not lost as these groups are essential in forming the amino acids. 

No 1 very mooch

C) reflection (i also looked up the other choices just to make sure)
