MCAT Question of the Day
    •

    Q:

    		 Unlike enzymatic amino acid synthesis, most chemical amino acid synthesis produces racemic mixtures. The difference is primarily due to which of the following?
    		 

    A

    		 Enzymes work at lower temperatures and are therefore able to catalyze more sensitive biochemical reactions.

    B

    		 Enzymatic reactions are usually stereospecific.

    C

    		 Chemical synthesis involves reagents that are racemic.

    D

    		 Chemical synthesis has a higher activation energy making it more likely to produce a racemic mixture.
