TRUE or FALSE For your responses please justify your answer. Nojustification for answer will recieve "needs work"rating.
13. Antibodies are Y-shaped molecules that have two identicalbinding sites. Imagine that you have
obtained an antibody that is specific for the extracellular domainof a receptor tyrosine kinase. When
the antibody binds the receptor, it brings together two receptortyrosine kinase molecules. If cells
containing the receptor tyrosine kinase were exposed to theantibody, would you expect the kinase to
be activated, inactivated, or unaffected? Explain yourreasoning.
14. Consider two different cell types differing in their abilityto respond to signaling molecule X.
Based on your knowledge of cell signaling pathways, suggest onepossible explanation for why one
cell can respond to signaling molecule X while the other onecannot.
