I am working on a code for enzyme kinetics. Initial concentration and rate constants are given. I have also use the dsolve command to solve for the differential equations below.
t = (0:0.4:40);
Ao = 3;
Bo = 2;
Co = 0;
So = 0.5;
Fo = 0;
k1 = 0.1;
k2 = 0.2;
k3 = 0.3;
k4 = 0.4;
k5 = 0.05;
A = simplify(dsolve('DA = (-k1*A)+(k2*S^2)+(k3*C*S)-(k4*A^2)','A(0) = Ai','t'))
B = simplify(dsolve('DB = (k1*A)+(k2*S^2)','B(0) = Bo','t'))
C = simplify(dsolve('DC = (-k3*C*S)+(k4*A*A)','C(0) = Co','t'))
S = simplify(dsolve('DS = (-k2*S*S)-(k3*C*S)+(k4*A*A)-(k5*S)', 'S(0) = So','t'))
F = simplify(dsolve('DF = (-k5*S)', 'F(0) = Fo','t'))
I am, however, having a problem trying to plot the output of A,B,C,S, and F as a function of time. Should I be using ezplot or plot to execute this code?
Thank you for your assistance.
Have a good day!
