#Unit 1. Molecules and their Interaction Relevant to Biology

For X, Kd is 1 micromole; for Y, Kd is 2 micromole & Because Y is half-saturated at a lower [B], it has a higher affinity for the ligand.
For X, Kd is 3 micromole; for Y, Kd is 6 micromole & Because X is half-saturated at a lower [B], it has a higher affinity for the ligand.
For X, Kd is 6 micromole; for Y, Kd is 2 micromole & Because Y is half-saturated at a lower [A], it has a higher affinity for the ligand.
For X, Kd is 2 micromoles; for Y, Kd is 6 micromole & Because X is half-saturated at a lower [A], it has a higher affinity for the ligand.
