Why is chewing bread for five minutes considered a chemical change?

The digestive process begins in your mouth. Some of the substances in the food -- sugars would be one category -- are completely broken into absorbable nutrients by saliva. So, for the bread -- a food containing chemicals that are chemically modified by saliva -- there will be chemical interaction in your mouth.

Which food would enzymes work more rapidly A slice of bread or an equal mass of bread crumbs?

Well, isn't that just a happy little question? Enzymes would work more rapidly on bread crumbs because they have a larger surface area compared to a slice of bread. This allows the enzymes to break down the food more efficiently, like a gentle breeze through the trees.

What is the single-celled organism that makes enzymes for bread making?

Most breads use commercially cultured yeast (a unicellular fungus) to make the bread rise.However sourdough bread uses a mixture of wild bacteria and wild yeasts to make the bread rise. The bacteria produce acids (e.g. lactic acid, acetic acid) producing the sour taste of this bread. The exact mixture of different species of microorganisms growing in the "starter" is unknown and varies widely from one location to another and even one bakery to another.
