Question

Which evidence supports the argument that amino acids can be a result of chemical reactions between sugar molecules?

A.
Sugar molecules contain carbon, hydrogen, and oxygen that can form amino acids.

B.
Sugar molecules contain side chains that can form amino acids.

C.
Sugar molecules contain an amino group that can form amino acids.

D.
Sugar molecules contain hydrogen, oxygen, and nitrogen that can form amino acids.

Answer 1

A.

Sugar molecules contain carbon, hydrogen and oxygen — three of the elements found in amino acids — so their composition supports the idea that chemical reactions involving sugars could produce amino-acid components (though nitrogen would still be required for complete amino acids).
