Question

25.Suppose you work for a Giant Food Processing Company (GFPC) that is evaluating various glucose polymers as potential food sources. The polymers were fed over the course of 4 weeks to laboratory animals whose digestive tracts work in the same way as human digestive systems. The overall average change in the body weight of each group of animals appears in the table below. Which of the following is likely to be true of the glucose polymers listed below? Polymer- Average weight change | -2-1-3-| +2-| +4- (kg)-» A. Glucose polymer #1 is likely to be composed of alpha links B. Glucose polymer #2 is likely to be composed of beta links C. Glucose polymer #3 is likely to be composed of beta links D. Glucose polymer #4 is likely to be composed of alpha links. E. Both and D are likely to be true.

Explanation / Answer

Ans. : E. Both B and D are likely to be true

It is because there is no enzyme in human digestive system which can break beta links, while alpha links can be broken easily to consume glucose polymer, consequently glucose polymer #4 becomes potential food source and can help to increase the weight of organism, while polymer #2 decreases the weight of organism as it can not be utilised.
