Document Summary

[e]t = [e] + [es: v0 = k2 [es, k2[e]t= vmax, k1[e][s]= kt[es] + k2 [es, v0= vmax [s] Km: km= (k -1 + k2) (units of concentration, i. e. m) (michaelis. K1 constant: when [s] = km, v0= vmax, km is substrate concentration that yields velocity, when [s] is lower than km, the velocity is slow, when [s] is higher than km, the velocity is fast. O2 -> fe (ii) shift out from plane to porphyrin plane: binding of oxygen sends signal, all life in this room relies on distance of 0. 4a xi. hemoglobin follows aspects of both the sequential and concerted models xii.
