The function of sugar in bread?

nothing lol

it shudnt be nothing lol because that isn't a very acurate answer the answer is because it give it a taste that people like!

That Nothing Lol Was The Answer off some 1 else.

Bread making uses flour ( the gluten in which makes the dough springy and stretchy ) , water ( to bind the mixture ), sugar and yeast - which is a living thing ( a fungi ). The sugar, or glucose, provides the energy for RESPIRATION.

Glucose + Oxygen -> Yeast -> Carbon Dioxide + Water

The yeast respires, leaving gas bubbles of Carbon Dioxide in the bread, which is what makes it rise, and the sugar ( as well as providing a tiny bit of flavour ) gives it the energy to do so.
