Given what you now know, what information is most likely to produce the correct answer?
What will be an ideal response?
If this molecule prevents ATP binding to the kinase, this will inhibit the reaction catalyzed by the
kinase. This is because the kinase acts to transfer the terminal phosphate of ATP onto its substrate. If
binding to ATP is inhibited, then the kinase will not have a source of phosphate nor the energy source
needed to drive this endergonic reaction. In fact, this is an approach that is used by multiple drugs that are
known kinase inhibitors.
