Answer:
A. ATP is a polymer of phosphates.
Step-by-step explanation:
ATP is not a polymer of phosphates. It is a rather a complex organic molecule that has its main function to provide energy.
Starch and glycogens are polysaccharides or polymers of glucose or simply put, they have glucose subunits.
Nucleotides are biological molecules consisting of 3 major sub units which are the nitrogenous base, the phosphate acid and the 5 carbon (ribose) sugar. They are the building blocks of DNA and RNA and hence monomers.
Amino acids are basically organic compounds that contain amine (-NH2) and carboxyl (-COOH) functional groups, along with a side chain (R group) specific to every amino acid molecule. They are bond together by a peptide bond between the -NH2 and -COOH group to furthet form polypetides. Proteins in the same vein are called polypeptides which is a chain of amino acids.
