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.

Alcoholic fermentation is a process carried out by certain organisms in the absence of oxygen. In this process, sugars such as glucose etc are broken down without oxygen into ethanol (alcohol) and carbon dioxide (CO2) by an organim called YEAST.

According to this question, Jose and Rema are making sourdough bread. The starter being fed has undergone fermentation (in the absence of oxygen). This means that the organism undergoing the fermentation produces ethyl alcohol and CO2 gas, creating pockets in the dough. Hence, making the dough to rise.
