This is glycogen. Look at those branches! What are the subunits (monomers / smallest units) of this polysaccharide?

Question

BlackTom AI · Accepted Answer

When considering a polysaccharide like glycogen, the fundamental subunits are monosaccharides that repeatedly join to form the polymer. 
Option 1: glucagon. This is a hormone involved in raising blood glucose levels and is not a monomer of glycogen; it has nothing to do with the repeating unit of the polymer. 
Option 2: glucose. This is the correct repeating unit; glycogen is a branched polymer of glucose molecules linked by α-1,4-glycosidic bonds with α-1,6 branches, meaning its smallest units are individual glucose molecules. 
Option 3: galactose. Although galactose is a monosaccharide, it is not the subunit used to build glycogen; glycogen specifically uses glucose as its monomer. 
Option 4: glycose. This is not a standard monosaccharide name in biochemistry; it is not the subunit of glycogen or a recognized simple sugar. 
In summary, the question hinges on identifying the fundamental building block of glycogen, which is the hexose sugar glucose rather than the other listed options. The reasoning clarifies why the other choices do not represent the monomeric units of glycogen.
