Executing these three forms should clarify things:
(let ((sym 'describe-function))
(funcall sym 'describe-function))
(let ((sym2 (make-symbol "describe-function")))
(funcall sym2 'describe-function))
(let ((sym2 (intern "describe-function")))
(funcall sym2 'describe-function))
To see the code ( if possible ) for describe-function do:
(describe-function 'describe-function)
Is should say something like:
describe-function is a function in "file"( underscored).
Go to "file" and press return up pops the file at the function
definition.
The one exception: a function which is an emacs primitive
imlemented in C. Then you will have to grep the source for it.
