Binding of cAMP by an R subunit of PKA occurs in a cooperative fashion; i.e., binding of the first cAMP molecule to CNB-B lowers the Kd for binding of the second cAMP to CNB-A.

Polygynous

In polygyny, one male mates with more than one female in a single breeding season, but females mate only with one male.

In species with male-male competition, males are often substantially larger than females, a phenomenon called sexual dimorphism.

The levels of insulin present in the body and the Kd for binding of insulin to its receptor on liver cells,

1.4 × 10−10 M (0.14 nM). The normal concentration of insulin in the blood is  5 × 10−12 M. 

The fraction of insulin receptors with bound insulin, [RL]/[RT], at equilibrium as 0.0344
