Still image from: Journey to the Microcosmos: How Does Yeast Make Bread?

Yeast is microorganism, and it releases enzymes that convert flour starch into sugar, which the cells absorb and metabolize. This process releases carbon dioxide gas, which forms bubbles that become trapped in the stretchy dough. During baking, the oven's heat expands the bubbles even further. Part of the "Journey of the Microcosmos" series.
