Why does bread rise?

It rises because lactic acid converts to pyruvic acid, with the addition of oxygen.

It rises due to the lactic acid that is produced as a waste product of fermentation.

It rises because yeast is capable of cellular respiration.

It rises because potential energy is converted to potential energy.

It rises due to the carbon dioxide that is released during alcoholic fermentation.
