Fly the aeroplane!
Quite right. Most aircraft will pitch up quite strongly if you apply full power while in the landing configuration. That includes singles like the Cessna 172. Try a full throttle go around at a safe recovery height in a C172 and it will yaw as well going beyond 45 degrees nose up, unless contained by prompt intervention. Grade 3 instructors should note and demonstration of this characteristic in the landing configuration should be covered during instructor courses.
The 737 is no different; except propeller driven types will also yaw as well as pitch up during a landing configuration go-around, and that has the potential to lead to an incipient spin.
From reading a recent ATSB accident report on a night go-around in a Cirrus 22, it would seem the expected strong pitch up and yaw after a bounced landing may not have been contained quickly enough by the pilot or instructor. . As the go-around was at night, instrument flying skill may also have been a factor. See:

Early intervention to contain a pitch up is vital; especially in IMC or dark night condition. One good reason students should not be sent solo at night until proved competent at go-arounds at the flare - not just at 200 feet.
