In case you go to a school that does you will have to teach a lab and the whatever + grade for that class. In order cases you just teach lab and grade. In some cases you just grade depending on what type of course (upperdivision. graduate). It will be somewhere around 15 to 20 hours a week depending on length of lab, no. of recitations, amount of grading, and of course required office hours
Too add to this, it also depends on what class you TA for. Normally you'll be starting out with a large lower division class and you'll be responsible for a section or two. Some of the older grad students TA grad classes, and there are no sections for that so all they do is grade and hold office hours.
