It is a little easier to help when you give specific examples of what you are attempting. However, I think Sequence will do what you want.
Suppose I have a function f defined as
f[a_,b_,c_d_]:= expression
then if
list = {a,b,c,d}
f[Sequence@@list] will do what you want. For example,
g[x_, y_, z_] := (x + y)/z
list = {x, y, z};
g[Sequence @@ list]
(x + y)/z
