Polysaccharides are polymers of monosaccharides. Homopolysaccarides are made up of only one type of monomer, whereas heteropolys
accharides are composed of at least two different kinds of monomers. Are starch, glycogen, cellulose, and chitin classified as homopolymers or heteropolymers?
A. All four polysaccharides are homopolymers.
B. All four polysaccharides are heteropolymers.
C. Starch is a heteropolymer, whereas chitin, cellulose, and glycogen are homopolymers.
D. Chitin is a heteropolymer, whereas starch, cellulose, and glycogen are homopolymers.
All four types of polysaccharides are homopolymers ie they are made up of repeating units of only one type of monomers.
Starch, glycogen and cellulose are made up of repeating monomeric units of glucose with the number of glucose units and the different linkage types different these molecules. E.g the linkage between glucose units in glycogen is alpha 1-4 linkages and in cellulose, we have glucose in beta 1-4 linkages.
In chitin, a derivative of glucose is present in repeating units, here, we have N-acetyl-D-glucosamine in beta 1-4 linkages.
An icicle grows as water drips down the structure and freezes adding to its length and thickness. Organisms grow via the addition of new cells to the organs it contains. These organs grow from the inside out over the entire structure.
