Initial activity equation
WebbEnzymes that display this behavior can often be described by an equation relating substrate concentration, initial velocity, K_m K m, and V_ {max} V max, known as the … WebbThere are three ways the calculator can compute the decay constant. i) If you have half-life, decay constant is computed using equation 3, you just need to key in the half-life and automatically get the decay constant. ii) If you have mean lifetime τ, the calculator will give you Decay constant (λ) using the equation. Decay constant (λ) = 1 ...
