A patient of diabetes mellitus excretes glucose in urine even when he is kept on a carbohydrate free diet. It is because
Options
- Afats are catabolised in adipose tissues to form glucose
- Bamino acids are catabolised in kidney to form glucose
- Camino acids are discharged in blood stream from liver
- Dglycogen from muscles is released in blood stream.
Correct answer
A. fats are catabolised in adipose tissues to form glucose
Step-by-step solution
A patient of diabetes mellitus is unable to produce or fail to utilise insulin hormone. Thus, he is unable to store glucose in the form of glycogen. Hence, he starts to excrete glucose in the urine even if a patient is kept on carbohydrate free diet, yet he excretes glucose in urine because high level of blood glucose not only depends on dietary carbohydrates but also on glycogenolysis (degradation of glycogen in liver) and gluconeogenesis (breakdown of fats into glucose in adipose tissues.
