How can I solve ode?

function dx=membrane(W,x)
k1c=2;
Kc1=0.2;
k2d=0.4;
k3e=400;
wf=100;
alfa=0.008;
kb=1;
ca0=0.6;
fa0=10;
ct0=0.6;
ft0=10;
v0=fa0/ca0;
ca=ct0*(x(1)/ft)*x(6);
cb=ct0*(x(2)/ft)*x(6);
cc=ct0*(x(3)/ft)*x(6);
cd=ct0*(x(4)/ft)*x(6);
ce=ct0*(x(5)/ft)*x(6);
fa=x(1,:);
fb=x(2,:);
fc=x(3,:);
fd=x(4,:);
fe=x(5,:);
y=x(6,:);
ft=x(1)+x(2)+x(3)+x(4)+x(5);
r1c=k1c*(x(1)-(x(2)*x(3)/K1c));
r2d=k2d*x(1);
r3e=k3e*(x(3)^2)*x(4);

dx(1,:)=-r1c-r2d;
dx(2,:)=r1c-(kb*ct0*(x(2)/ft));
dx(3,:)=r1c-r3e;
dx(4,:)=r2d-(r3e/2);
dx(5,:)=r3e;
dx(6,:)=-alfa*ft/(2*x(6)*ft0);
end
