MUSCLE PHYSIOLOGY

Detailed explanation-1: -Alcoholic fermentation is a biotechnological process accomplished by yeast, some kinds of bacteria, or a few other microorganisms to convert sugars into ethyl alcohol and carbon dioxide.

Detailed explanation-2: -Since only alcoholic fermentation produces CO2, Organism A will have the greater rate of CO2 production. In an aerobic environment, both organisms will use aerobic respiration. Both organisms should produce the same amounts of CO2.

Detailed explanation-3: -As the yeast feeds on the sugar, it produces carbon dioxide. With no place to go but up, this gas slowly fills the balloon. A very similar process happens as bread rises. Carbon dioxide from yeast fills thousands of balloonlike bubbles in the dough.

Detailed explanation-4: -Summary: Why do some yeast cells produce ethanol? Scientists have wondered about this apparent waste of resources for decades. Now scientists think they have a solution: yeast cells produce ethanol as a ‘safety valve, ‘ to prevent overload when their metabolic operation reaches a critical level.
