Recall that the macronutrients carbohy- drates, fats, and proteins provide energy; thus, we need to consume them in relatively large amounts. In contrast, the micronutrients, vitamins and minerals, are needed in very small amounts. They are nev- ertheless essential to our survival, assisting critical body functions such as energy metabolism and the formation and maintenance of healthy cells and tissues. Much of our knowledge of vitamins and minerals comes from accidental observations of...

CBSE Biochem Lesch-Nyhan Syndrome: what causes it and what are manifestations? - correct answersHGPRT deficiency in purine salvage pathway (this enzyme normally converts hypoxanthine to IMP and guanine to GMP). This deficiency leads to excessive Uric acid production and de novo purine synthesis. It is X linked recessive. Symptoms: hyperuricemia, gout, aggression / self mutilation, mental retardation, dystonia. Treatment for Lesch-Nyhan? - correct answersAllopurinol / febuxostat second ...

What is the maturation and life cycle of enterocytes (crypts, villi, sloughing etc.) - correct answer The crypts which located in the pits of villi contain stem cells that can differentiate to enterocytes, and the enterocytes mature as they migrate up. The life cycle of enterocytes is 72 hours. Once enterocytes have reached the top of villi, they are sloughed off, and are either digested or excreted in feces. Uptake - correct answer compounds being transported into enterocytes Absorption -...
