It is the action of the yeast that causes breads to rise. Yeast as it grows produces carbon dioxide this is trapped in the bread dough and causes the dough to rise.
Leavening with yeast is a process based on fermentation, biologically changing the chemistry of the dough or batter as the yeast works. Yeast leavening requires proofing, which allows the yeast time to reproduce and consume carbohydrates in the flour.

Why are biscuits quick bread?
Quick breads such as muffins, unlike yeast breads, can be baked immediately after the ingredients are mixed. In other words, there is no need to wait for leavening to occur before baking the muffins because they rise during baking. Therefore, they are relatively quick to make. Yeast breads on the other hand require a lot of time for leavening before baking and are much more time consuming.Source: "Understanding Food" by Amy Brown
