D
Monosaccharides
Verified step by step guidance
1
Understand that proteins are large, complex molecules that play many critical roles in the body. They are made up of smaller units called monomers.
Identify the four options given: Amino acids, Fatty acids, Nucleotides, and Monosaccharides.
Recall that amino acids are the monomers that link together to form proteins. Each protein is made up of a unique sequence of amino acids.
Recognize that fatty acids are components of lipids, nucleotides are the building blocks of nucleic acids like DNA and RNA, and monosaccharides are simple sugars that form carbohydrates.
Conclude that the correct monomer for proteins is amino acids, as they are the fundamental building blocks that form the structure of proteins through peptide bonds.
