Question

The enzyme, whose blood levels is increased in patients with Duchenne muscular dystrophy is
A. Carbonic anhydrase
B. Dystrophin kinase
C. Adenosine triphosphate
D. Creatinine phosphokinase

Answer 1

Hint:
Before we proceed into the problem, it is important to know the definitions of Duchenne muscular dystrophy.
Dystrophin is a crucial muscle protein that is produced by a gene that is mutated in DMD. Bundles of fibers make up muscles (cells). The normal functioning of muscle cells is maintained by a collection of interdependent proteins along the membrane surrounding each fiber. Duchenne muscular dystrophy results from the absence of dystrophin, one of these proteins.

Complete answer:
The enzyme, whose blood levels is increased in patients with Duchenne muscular dystrophy is Creatinine phosphokinase. This enzyme helps to break down the substance that causes the disease, called myostatin. Myostatin blocks muscle growth and development by restricting the amount of protein that's produced. Elevated levels of CBS may lead to an improved quality of life for those suffering from this devastating condition.
Creatinine phosphokinase is a protein that helps to regulate the levels of calcium and phosphate in the body. It plays an important role in energy production by converting glucose into energy-rich ATP, which can be used for various processes in the body.
Therefore, the enzyme, whose blood levels is increased in patients with Duchenne muscular dystrophy is Creatinine phosphokinase.

Option ‘D’ is correct

Note:
When there is too much creatinine phosphate build-up due to diseases or injury, creatinine phosphokinase can become impaired. This will lead to decreased energy levels, muscle weakness, exercise intolerance, and fatigue. If you are feeling tired all the time or experiencing any of these symptoms, it may be helpful to seek medical attention as your creatinine phosphokinase level may need to be checked. Creatinine can be detected using this enzyme, which can then help to guide treatment decisions related to kidney injury or kidney disease.
