As I was drinking the morning coffee with a sweet mexican bread I started to wonder how did our ancestors stumble upon yeast and coffee. Yeast is a fungi that is used to make bread, wine, and beer. With the lack of oxygen the yeast ferments to produce energy and converting the sugars into carbon dioxide and ethanol; thus producing alcohol and a delicious piece of bread. Even though our ancestors didn't know it but they were biochemists! Did someone accidentally placed the yeast with flour and noticed that the yeast made the flour mixture swell up and tadaaa, bread was produced. I don't know how it was discovered but one thing for sure yeast was used many years ago. It is even written in the Bible!
I am thankful for the discovery of yeast because I can enjoy my piece of mexican bread every morning along with my coffee. Plants and fungi are very important to everyone.
