Water-soluble vitamins The enzyme(s) called break(s) down the substrate called A. lactase; glucose peptidases; proteins lipases; micelles lactose; lactase nucleases; nucleotides 62. cells by Lipids are transported to the surface of the intestinal absorptive and are then processed into fat droplets; micelles fat droplets; chylomicrons micelles; fat droplets micelles; chylomicrons D. The three most abundant classes of nutrients are carbohydrates, proteins, and minerals fats, proteins, and carbohydrates proteins, nucleic acids, and carbohydrates triglycerides, starches, and proteins proteins, fa D.Explanation / Answer
50. A . Triglycerides are absorbed by lacteals of small intestine.
The lacteals are lymphatic vessels in villi of small intestine which absorb digested fats.
Among the options triglycerides are the digested fats.
57. E. The enzyme called nuclease breaks down the substrate called nucleotide.
Lactase breaks down lactose, so options A and D are not accurate.
Lipase breaks down fats so option C is not accurate .
Pepsin breaks down proteins so option B is not accurate.
62. D. Lipids are transported to the surface of the intestinal absorptive cell by micelles and are then processed into
chylomicrons.
Micelles break down digested lipids to be small enought to enter through the micro villi.
Then the fatty acids leave the micelle and enter through the enterocyte and get re arranged into tri acyl
glycerol .
These get packaged into lipoproteins which enter circulation through the lacteals.
63. B. The three most abundant classes of nutrients are fats,proteins and carbohydrates.
Fats, proteins and carbohydrates are macro nutrients which have to be ingested by the body in order to
survive.
Minerals are found in trace quantities and nucleic acid and triglycerides are synthesised by body.
Starch is a source of carbohydrate.
