Question
The structure of monomers affects the structure and function of the polymers they form. Which rowdescribes the structural features of polysaccharides made from alpha-glucose and beta-glucose?Monomer Polymer Shape of polymerA. alpha-glucosebeta-glucosestarchcelluloseunbranched, straightbranched, helicalB. alpha-glucosebeta-glucosestarchcellulosebranched, helicalunbranched, straightC. alpha-glucosebeta-glucosecellulosestarchbranched, helicalunbranched, straightD. alpha-glucosebeta-glucosecellulosestarchunbranched, straightbranched, helical
Solution
The correct answer is B. alpha-glucose forms starch which is branched and helical, while beta-glucose forms cellulose which is unbranched and straight. This is due to the different ways the glucose monomers can bond to each other, resulting in different 3D structures and therefore different properties of the polymers.
