Question

What does the difference in co2 levels in the tube containing 1 ml of yeast versus that containing 3 ml of yeast tell you about alcoholic fermentation?

Answer 1

tube containing1 ml of yeast. A small amount of CO2 was produced over the course of the experiment. tube containing 3 ml of yeast. Since yeast produces the enzymes and other machinery that are used for alcoholic fermentation, the more yeast that is used in the experiment, the more CO2produced and the faster the rate of alcoholic fermentation. 
The tube containing the most yeast will produce the most CO2 and will have the fastest rate of alcoholic fermentation.

Answer 2

Answer: The amount of yeast is directly proportional to the level of CO2 which hence directly proportional to alcoholic fermentation

Explanation: Due to increased amount of yeast activity of yeast cell increases which increase the amount of CO2 hence increasing the rate of fermentation.
