Answer is D (proline)
Glcolysis pathway is the metabolic pathway,which covert glucose into pyruvate and lactate.
Serine,Cysteine, and Glycine are formed from 3-Phosphoglycerate.But,Proline is not formed.Proline is non essential aminoacid,Glutamate is the precursor of proline and arginine.serine is the precursor of glycine and cysteine.Serine is synthesised from 3-phosphoglycerate,an intermediate in glycolisis.Oxidation to 3-phosphohydroxypyruvate is the first step.The alpha ketoacid transmitted to 3-phosphoserine,then hydrolised to serine.
Serine +tetrahydrofolate 
glycine + methylenetrahydrofolate +H2O
In glycine formation ,the side chain methyl group transffered to tetrahydrofolate.

Which three statements about amino acids are true? Use this chart of amino acid structures for reference. Lysine has one stereocenter (chiral center). Methionine is a thiol. The Leu side chain does not form hydrogen bonds with other amino acids. The form of glycine used by the human body is D-glycine. Ser and Thr are polar amino acids. Proline has an overall charge at physiological pH (7.4).
