Question 10

While watching late night TV,John noticed a commercial that was advertising a product that allows you to eat all the fat that you want and you won't gain any weight.In order to accomplish this feat,the product claims that it prevents the fat from being digested.Which is the best scientific explanation for how this is accomplished?

Accepted Answer

A) The product denatures,or prevents the enzyme lipase from functioning.Lipase digests fat droplets to monoglycerides and fatty acids which can then be absorbed by the body which leads to weight gain. 
B) The product denatures,or prevents the enzyme pancreatic amylase from functioning.Pancreatic amylase digests fat droplets to monoglycerides and fatty acids which can then be absorbed by the body which leads to weight gain. 
C) The product denatures,or prevents the enzyme lipase from functioning.Lipase digests fat droplets to glucose which can then be absorbed by the body which leads to weight gain. 
D) The product denatures,or prevents the enzyme trypsin from functioning.Trypsin digests fat droplets to monoglycerides and fatty acids which can then be absorbed by the body which lead to weight gain. 
E) The product denatures,or prevents the enzyme nucleases from functioning.Nucleases digests fat droplets to monoglycerides and fatty acids which can then be absorbed by the body which lead to weight gain. 
A) The product denatures,or prevents the enzyme lipase from functioning.Lipase digests fat droplets to monoglycerides and fatty acids which can then be absorbed by the body which leads to weight gain.
