Proteins bind selectively to small-molecule targets called ligands. The selection of one ligand out of a mixture of possible ligands depends on the number of weak, noncovalent interactions in the protein's ligand-binding site
Where is the binding site typically located in the protein structure?
(a) on the surface of the protein
(b) inside a cavity on the protein surface
(c) buried in the interior of the protein
(d) forms on the surface of the protein in the presence of ligand
(b)

In your research, you have discovered that Protein X is often ubiquitinated in people with a certain disease. What would you predict about levels of Protein X in these patients?
A. Levels of Protein X will be low due to degradation in the proteasome. B. Levels of Protein X will be the same, just carrying a ubiquitin tag. C. Levels of Protein X will be increased due to transcriptional activation. D. Levels of Protein X will be decreased due to negative feedback on transcription. E. Levels of Protein X will be increased due to protection from degradation.
