... (steps 1 and 2) and cycle 2 (steps 3 and 4) (Eqn 7) and the values of a, c and b only depend on the K S value (Eqn 8). The concentra- tions of interconvertible forms are: c ¼ a ¼ 1 þ K S 3 and b ... of a and c with respect to v 14 . In particular, for H ¼ 1 there is an abrupt decrease of a in parallel with an increase in c and flux through cycle 2. b and flux through cycle...
