Answer 1

In Explicit transaction mode, you will need to start a transaction explicitly. In Implicit transaction mode, a transaction is automatically started after each commit. So you will only have to commit.

Since the transaction is started 'implicitly', you will not see an explicit 'BEGIN' in the logs. :)

By default the database operates in explicit transaction mode with autocommiting transactions enabled. That actually meand that unless an explicit transaction is started using BEGIN TRANSACTION, every data modification is started in a separate transaction which is committed after the statement. That allows the database to rollback an entire statement when it fails (for instance a bulk insert, or an insert that modifies other data in a trigger).
