Question
1) These building-blocks make up the molecules that play an important structural role in the cell wall of plants.2) These building-blocks make up the molecules that transport oxygen in your blood.
3) These building-blocks make up the molecules that carry instructions on how to make proteins from chromosomes to the location of protein production.
4) These building-blocks are part of the molecules that are the major structural component in cell membranes.
My choices (For each one) are fatty acids, simple sugars, amino acids, and nucleotides. I thought that the answers, respectively, were: simple sugars, fatty acids, nucleotides, and amino acids, but apparently that is incorrect.
Explanation / Answer
You're almost there... 1) is simple sugars because the molecules that make up the cell wall of plants is cellulose, which is a polysaccharide made of thousands glucose units. 2) Is Amino acids... which make up the primary structure of hemoglobin, the molecule that transports oxygen in your blood. 3) Nucleotides, as you know store our genetic information and the basic instructions for making proteins in a cell. 4) Fatty acids. Fatty acids make up the lipid bilayer cell membrane.
