Jose and Rema are making sourdough bread. They have been feeding the starter dough for a week now, and it has undergone lactic acid fermentation. They mix the dough and add a portion of the starter, which will give the bread its famous texture and sour flavor. What process will occur next to make the dough rise? A
Alcoholic fermentation takes place and ethyl alcohol and CO2 gas are formed, creating pockets in the dough.

B
Alcoholic fermentation takes place, and the yeast give off oxygen, creating pockets in the dough.

C
Alcoholic fermentation takes place, and during the Krebs cycle, CO2 is produced, creating pockets in the dough.

D
Alcoholic fermentation takes place, and the H2O byproduct of the electron transport chain vaporizes to create pockets in the dough.
