A biochemist is designing a new drug that will mimic the shape and function of a particular intercellular signaling molecule. Therefore she must produce a molecule that will bind to the receptor protein and...
A. produce a cellular response by altering the Na+/K+ pump located near the receptor site.
B. induce a change in the receptor molecule shape, which will ultimately prevent a cellular response.
C. induce a change in the receptor molecule shape, which will ultimately produce a cellular response.
D. induce a change in the phospholipid bilayer that causes a polar reversal allowing the molecules to be endocytose (engulfed).
