Quoting won't work, use any array:
#define it
READ_USER_INPUT_IF_IN_DEBUG_MODE=(read -p 'press any key to continue:')
#calling it
"${READ_USER_INPUT_IF_IN_DEBUG_MODE[@]}"
See this page for more details on Bash arrays handling.

One thing though. I need that the command"${READ_USER_INPUT_IF_IN_DEBUG_MODE[@]}"will not return error in case of empty variable. Setting it to empty string resulting incommand not found
