In designing your vaccine, you will need to choose an antigen orantigens to stimulate the adaptive response. All antigens are notcreated equal--there are certain characteristics that make moreeffective antigens. Which of the following best describes whymolecules such as glycoproteins are more effective antigenscompared to molecules such as starch?
-In general, proteins stimulate stronger immune responses thancarbohydrates such as starch. | |
-Glycoproteins have greater molecular mass compared to starch;therefore, they will elicit a stronger immune response. | |
-Since starch is a polymer of glucose (which is used byeukaryotic cells for energy), it is not recognized as foreign. | |
-Glycoproteins contain a variety of shapes and subunits thatcontribute to the overall complexity of the molecule. |
