Explanation / Answer

75. Option a is correct. hGH (human growth hormone) and IGFs (insulin like growth factors interact with insuline to modulate its control of carbohydrate metabolism.

79. Option b is correct. These are the symptoms of traveller's diarrhoea. Abdominal cramping and fever is the characteristic symptoms of traveller's diarrhoea. Irritable bowel's syndrom shows the presence of mucus while peptic ulcer shows the presence of blood in stool. diverticulitis also shows the presence of blood in stool. Inguinal hernia have pain in groin region.

84. Option d is correct. Insulin decreases the level of glucose in blood.

86. Option e is correct. Thiamine is also called vitamine B1 which is water soluble. All other options show fat soluble vitamins (A, D, E and K) which required fat for their absorption.

87. Option a is correct. Production of ATP by oxidizing glucose to carbondioxide and water is not the charestrictic of absorptive state. This occurs after complete absorption and distribution of glucose to the tissues. Rest all options mention the characteristics of absorptive state.
