Cater for reform, and respond (5)
I believe the answer is:
react
'respond' is the definition.
(to react to something is to respond to it)
'cater for reform' is the wordplay.
'for reform' is an anagram indicator (I've seen this in other clues).
'cater' with letters rearranged gives 'REACT'.
'and' acts as a link.
(Other definitions for react that I've seen before include "Hit back" , "Respond to a stimulus" , "Respond emotionally" , "provide an answer" , "What a chemical might do" .)
