How to pass query into store procedure as a parameter in sql

Question

I want to pass the query into the stored procedure as a parameter and execute the stored procedure.
I want to do like this one,

DELIMITER $$
CREATE PROCEDURE function1(query1, query2, query3)
BEGIN
  DECLARE EXIT HANDLER FOR SQLEXCEPTION,SQLWARNING
  rollback;

  start transaction;
    // I want to execute query 1 here
    // I want to execute query 2 here
    // I want to execute query 3 here
  commit;
END

Please help me here how can I pass the whole queries into the stored procedure as a parameter and execute parallel.

Thank you in advance

You can use EXECUTE IMMEDIATE to run the queries. EXECUTE IMMEDIATE 'QUERY1'; will execute QUERY1. As pointed out by @sticky bit beware of malicious statements.
