Cleave hydroxyl groups of dietary complex carbohydrates molecules. C. Digest dietary complex carbohydrate in the mouth and the stomach. D. Join two simple sugars together to form complex carbohydrate molecules. E. Allow passage of simple sugars inside the intestinal cells. Table 3
  2. Which of the following transporters absorb both glucose and galactose inside the renal and intestinal cells? A. GLUT B. GLUT C. SGLT D. GLUT E. GLUT

Table 4

  1. A urine test is positive for fructose. Which of the following enzymes is decient in fructosuria? A. Aldolase B B. Phosphoglucomutase C. 4-Epimerase D. Fructokinase E. Galactokinase Table 5

  1. What is the metabolic function of the two subunits of lactose synthase? A. Lactalbumin synthesizes prolactin and galactosyltransferase synthesizes cortisol. B. Lactalbumin synthesizes lactoglobulin and glycosyltransferase synthesizes casein. C. Lactalbumin increases the catalytic rate of galactosyltransferase during the synthesis of lactose. D. Lactalbumin synthesizes colostrum and galactosyltransferase synthesizes mature milk. E. Lactalbumin converts glucose to galactose and galactosyltransferase degrades galactose. Table 11

  1. Why are glycosylated proteins clinically important for diabetic patients only? A. They form surface receptors for connection and neu- ral communication between cells. B. They are important components of the coagulation cascade and in diagnosing coagulation disorders. C. They provide lubrication for cell surfaces and pro- tection against pathogenic bacteria. D. They cause thickening of blood vessels impairing delivery of nutrients and gas exchange in the cells. E. They can function either as hormones or enzymes for metabolic and reproductive function.
