Variations of the Bohr coefficient with Po2 are given by Eq. 4. WebDec 2, 2024 · The Hill Equation. The degree of cooperativity is determined by Hill equation (Equation 4.6.1) for non-Michaelis-Menten kinetics. The Hill equation accounts for allosteric binding at sites other than the active site. n is the "Hill coefficient." (4.6.1) θ = [ L] n K d + [ L] n = [ L] n K a n + [ L] n. where.
