What helps bake products rise?

There are several things which help baked products rise. The one you use often depends on what it is you are baking. For homemade breads, yeast is what is used to make the bread rise. For cakes, pancakes, biscuits and cornbread, baking soda or baking powder is what's used to make them rise. Also, eggs are the 'leavening' agent in some baked goods, such as pound cake.
