Question

If a person is suffering from a disease of muscular dystrophy, he will eliminate one of the following in large amount in his urine.

• A. Sulphates
• B. Glucose
• C. Creatinine
• D. Water

Answer 1

The correct option is C Creatinine

Creatine is present in the tissues ( muscle, brain, blood etc.). It is stored in muscle as high energy phosphate and provide ATP at the time of muscular contraction.
ADP + Phosphocreatine ---> ATP + Creatine (in presence of enzyme Creatine phosphokinase)
Increased output of creatine in urine is referred to as creatinuria. Diminished creatinine (an anhydride of creatine) excretion and creatinuria is observed in muscular dystrophy, in which muscles progressively deteriorate. High levels of serum creatine phosphokinase are also observed during muscular dystrophy.

So, the correct answer is option C.
