Which is not a symptom of hyperglycaemia?
1. Loss of weight
2. Breakdown of muscle tissue
3. High blood glucose level
4. Diplopia
Which of the following statements regarding glucagon is false?
1. It is secreted by -cells of Langerhans.
2. It acts antagonistically to insulin.
3. It decreases blood sugar level.
4. The gland responsible for its secretion is heterocrine gland
A patient of diabetes mellitus excretes glucose in urine even when he is kept in a carbohydrate free diet. It is because:-
1. fats are catabolised in adipose tissues to form glucose
2. amino acids are catabolised in kidney to form glucose
3. amino acids are discharged in blood stream from liver
4. glycogen from muscles is released in blood stream
Select the correct statement about hormones and their actions.
1. Parathyroid hormone increases absorption of the body.
2. Insulin and glucagon helps to maintain blood sugar levels.
3. Old aged people have weak immunity due to increased activity of thymus.
4. Osteoporosis in women occurs due to increased levels of oestrogens.
The glucose homeostasis in blood is maintained by
(1) Insulin
(2) Glucagons
(3) Both 1 and 2
(4) None of these
The condition of prolonged hyperglycemia leads to
(1) Diabetes Insipidus
(2) Diabetes mellitus
(3) Glycosuria
(4) Both 2 and 3

1. Stimulates glycogenolysis
2. Stimulates glycogensis
3. Inhibits cellular glucose uptake and utilisation
4. Stimulates gluconeogenesis
1. Increases glycogenesis
2. Increases glycogenolysis
3. Promote oxidation of glucose and conversion of glucose into glycogen in muscles as well as liver cells
4. Increase uptake of amino acids by liver and muscles
