There are two correct products listed, I am not certain if your teacher meant that, but those bubbles are a product.
I suspect the teacher missed that point.
The process of alcoholic fermentation is a metabolic pathway that converts glucose into ethanol and carbon dioxide through the action of enzymes called alcohol dehydrogenases. Therefore, the correct answers are:
I. ethanol
III. carbon dioxide
To arrive at this answer, we can recall some basic knowledge about the products of alcoholic fermentation. Alcoholic fermentation occurs in certain microorganisms, such as yeast, when oxygen is limited. During this process, glucose (a type of sugar) is broken down into ethanol (alcohol) and carbon dioxide (a gas). This type of fermentation is commonly used in baking and brewing industries to produce products like bread, beer, and wine.
The other options, lactic acid and oxygen, are not produced in significant amounts during alcoholic fermentation. Lactic acid fermentation, on the other hand, occurs in certain bacteria and even in our own muscles during intense exercise. Oxygen is not a product of fermentation but rather a reactant in the process of cellular respiration, which is the main pathway for energy production in most organisms.
