From what I remember yeast is able to break down starch but at a VERY slow process since the molecule of starch is much more complicated then say glucose.

Yes. Yeast is a type of single cell fungus. Fungi use extracellular digestion. They excrete enzymes and absorb the broken down molecules. Yeast breaks down starch as an energy and carbon source, but it also needs nitrogen and some minerals. Because fungi tend to grow in nitrogen poor environments, they are extremely efficient at scavenging and keeping the nitrogen needed to make proteins.

they just break them down into less complex substance such as alcohol and carbon-di-oxide
