List of parameters to manipulate from an external list

I am trying to achieve the functionality of the following command:

Manipulate[ z, {z, 0, 1}]

but with passing the list of parameters into Manipulate from and external list, e.g.

list = {z, 0, 1};
Manipulate[ z, list ]

but with this syntax I recieve the following error:

Manipulate::vsform: "Manipulate argument \!\(ToExpression[{\"z\", 0, 1}]\) does not have the correct form for a variable specification"

How can I overcome this?
