Question

actate Fermentation Alcoholic Fermentation Description Starts with glycolysis Generates pyruvate at the end of glycolysis Does not generate any CO2 Starts with six-carbon glucose and ends with two molecules of a two-carbon by-product 000 Many people enjoy sugary soda pop because it is fizzy. This fizziness is the result of pressurized gas that is artificially added during the manufacturing process. People have also enjoyed the fizziness of beer and sparkling wine for thousands of years, but the gas in beer and sparkling wine is a natural product that does not need to be artificially added. Beer and wine are made when yeast ferments the sugars found in grains or grapes. Of the following choices, which pair correctly identifies the gas found in beer and sparkling wine and the type of fermentation the yeast uses? Carbon dioxide and lactate fermentation O Oxygen and alcoholic fermentation O Carbon dioxide and alcoholic fermentation O Oxygen and lactate fermentation Tetra Images / Getty Images

Answer 1

1. Starts with glycolysis - Lactate fermentation and Alcoholic fermentation

Glycolysis occurs in the cytoplasm of all living organisms. This process produces pyruvate. Pyruvate is produced both in yeast (where it is subject to alcoholic fermentation) and in muscle cells (where it is subject to lactate fermentation to produce lactate).

2. Generates pyruvate at the end of glycolysis - Lactate fermentation and alcoholic fermentation

3. Does not generate any CO2 - Lactate fermentation

Please refer the image attached below.

4. Starts with six-carbon glucose and ends with two molecules of a two carbon by-product - Alcoholic fermentation

Please refer the image attached below.

The gas found in beer and sparkling wine is carbon dioxide and the type of fermentation which occurs is Alcoholic fermentation. So the option is c - carbon dioxide and alcoholic fermentation.
