Metoprolol loses beta-receptor selectivity at high doses and in poor metabolizers. If drug is administered for tachycardia secondary to pheochromocytoma, it should be given in combination with an alpha blocker (which should be started before metoprolol is started)
Best Answer: Amino Acids are the monomers that make up protein.... and enzymes are a type of protein. (i.e. the peptide chain is the polymer made of amino acid monomers). There may be a-helixes and b-sheets formed (secondary structure). This chain then folds (into tertiary).
Monomers that make up Nucleic Acids. 1  Nucleic acids serve a much broader role in cell activity than simply the storing of genetic information (DNA) or the coding of protein amino acid sequence (RNA). 2  Smaller nucleic acids, the monomers serve as the building blocks for the larger polymers of DNA and RNA and also as energy carriers.
