Receptor Occupancy

Half Signal Gives One Half

A signal equal to the half-signal constant gives half occupancy. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Signal equals the half-signal constant

The signal is 6 and the half-signal constant is 6.

6+6=126+6=12
Receptor occupancy ledgerA half-signal constant turns signal into a bound fraction.61/2

Signal over signal plus half-signal gives one half

The low-side bound fraction is 1/2.

6/12=126/12=\frac{1}{2}
