Using the y -intercept, we calculate Vmax as Vmax = 1 / y −intercept = 1 / 1.708 mol = 0.585 mol and using the slope we find that Km is Km = slope × Vmax = 0.7528 molimM × 0.585 mol = 0.440 mM
Nettet5. feb. 2024 · Then Y = L/ [K D +L] = L/ [100L + L] ≈1/100. This implies that irrespective of the actual [L], if L = 0.01 K D, then Y ≈0.01. L = 100 K D (i.e. L >> K D ), which implies that K D = L/100. Then Y = L/ [K D +L] = L/ [ (L/100) + L] = 100L/101L ≈ 1. This implies that irrespective of the actual [L], if L = 100 Kd, then Y ≈1. L = K D, then Y = 0.5
