Question

Students are studying the rate of yeast fermentation under different conditions. Glucose is a monosaccharide. Sucrose is a

disaccharide
What do you predict would happen if a 6th test tube was added containing fruit juice and yeast?

A) Fermentation would not occur without sugar.

B) Fermentation would occur at a similar rate to that of glucose.

C) Fermentation would occur faster due to the acidic nature of the juice.

D) Fermentation would occur, but very slowly because of the extra time
required to break down the juice.

Answer 1

B) Fermentation would occur at a similar rate to that of glucose.

Step-by-step explanation:

Answer 2

The correct option is B. Fermentation would occur at a similar rate to that of glucose.

Step-by-step explanation:

Fermentation can be described as a process in which alcohol is released by using sugars. In fruit juices, fructose is present mainly to get the sweetness. It is used as a substitute for glucose because fructose is more sweeter than glucose. Both fructose and glucose are monosaccharides with the formula C6H12O6. The only difference is in the arrangement of molecules in the atoms of these compounds. Hence, the rate of fermentation would be same for these two sugars.
