Even the conduct of the simplest regulated system cannot be explained aside from mathematically.’
Competitive/reversible antagonism: It is a phenomenon where aggressive antagonists contend with agonists for a common binding website on the receptor.
A past paper discusses the mathematical implementation of your product (Peper 2004b).
