Epithelial cells of the intestine involved in food absorption have on their surface - Zymogen granules Pinocytic vesicles Phagocytic vesicles Microvilli a young infant may be feeding entirely on mother's milk which is white in colour but the stools which the infant passes out is quite yellowish. What is this yellow colour due to ? Pancreatic juice poured into duodenum Intestinal juice Bile pigments passed through bile juice Undigested milk protein casein Fructose is absorbed into the blood through mucosa cells of intestine by the process called : active transport facilitated transport simple diffusion co-transport mechanism The difference between Marasmus and Kwashiorkor is that : (1) Marasmus is a deficiency of just proteins while Kwashiorkor is due to a deficiency of both proteins and calories. (2) Marasmus is caused by deficiency of Vitamin B while Kwashiorkor is caused by the deficiency of Vitamin D. (3) Marasmus is caused by a calorie deficiency while Kwashiorkor is caused by protein deficiency. (4) Marasmus is a simultaneous deficiency of proteins and calories while Kwashiorkor is due to just protein deficiency unaccompanied by calorie deficiency The cuboidal epithelium with brush border of microvilli is found in: Proximal convoluted tubule of nephron Ducts of salivary glands Inner lining of fallopian tubes Lining of stomach Select the correct match of the digested products in humans given in column I with their absorption site and mechanism in column II Glycine, glucose – Small intestine, active absorption Fructose, Na + – Small intestine passive absorption Glycerol, fatty acids – Duodenum, move as chilomicrons Cholesterol, maltose – Large intestine, active absorption Given below are two statements : Statement I : Fatty acids and glycerols cannot be absorbed into the blood. Statement II : Specialized lymphatic capillaries called lacteals carry chylomicrons into lymphatic vessels and ultimately into the blood. In the light of the above statements, choose the most appropriate answer from the options given below: Both Statement I and Statement II are incorrect Statement I is correct but Statement II is incorrect Statement I is incorrect but Statement II is correct Both Statement I and Statement II are correct
