I felt "begin and commit" was a bit wordy but it works.
So, I was worried that "manage multiple transactions" could imply something like savepoints, which can be managed by functions. It is really the top-level begin/commit that is unique for procedures.
Functions is executed under outer transaction every time - rollback to save point hasn't impact on outer transaction. Inside procedures (in special case) can be transactions ended (by statements COMMIT or ROLLBACK). Immediately is started new transaction.
