Baking is presented as an example of biotechnology where yeast, a microorganism, is used. Yeast respires anaerobically to produce carbon dioxide, which leavens the dough, and the yeast cells are killed during the baking process.
Baking exemplifies biotechnology through the use of yeast, a microorganism. Yeast undergoes anaerobic respiration, producing carbon dioxide that causes dough to rise. The yeast is ultimately killed during the baking process.
