  2. The blood sugar level is high

  3. The blood sugar level is normal

  4. The sugar absorption is impaired
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Excessive alcohol consumption causes chronic inflammation of the pancreas i.e. pancreatitis, which impairs its ability to secrete insulin. Insulin is a hormone necessary for maintaining the normal concentration of glucose in the blood. It promotes the conversion of glucose to glycogen i.e. glycogenesis for storage in liver and muscle cells. Deficiency of insulin raises the blood sugar glucose and may lead to insulin-dependent diabetes mellitus. Thus the correct answer is option B.
