CBSE Class 10 Science 2026: question 12(A)

Set in the CBSE Class 10 board exam of 2026, paper 31/4/1, section A, question 12(A), for 2 marks. Try it first; the hints and our step-by-step solution are below.

Q12(A) · 2 marks · Very short answerCompetency-basedControl and Coordination

Varun is diabetic. His latest ultrasound reports showed a blockage in his pancreatic duct. How will this affect the dual functioning of the pancreas?

Source: official question paper from cbse.gov.in (PDF). See it in the full 2026 board paper, set 31/4/1.

Hints

Open one hint at a time and try again before the next.

Hint 1

The pancreas works both as an exocrine gland and as an endocrine gland. Which of these uses the duct?

Hint 2

Hormones go straight into the blood. Think about what diabetes already says about insulin.

Step-by-step solution

Each step shows the marks it earns, as an examiner would award them. Checked by an independent re-solve from the question paper.

  1. Exocrine (digestive) function: Pancreatic juice contains trypsin, lipase and pancreatic amylase, and it reaches the small intestine through the pancreatic duct. With the duct blocked, these enzymes cannot reach the intestine. Digestion of proteins, fats and carbohydrates will therefore be impaired.

    1 mark

  2. Endocrine (hormonal) function: Insulin is made by the islets of Langerhans and passes directly into the blood without using the duct, so the blockage does not affect this route. However, Varun is diabetic, so his insulin secretion is already deficient and his blood sugar control remains affected.

    1 mark

Answer: Digestive function is affected because pancreatic enzymes cannot reach the small intestine. The hormonal function (insulin) is not affected by the blockage but is already impaired because he is diabetic.

Where the marks are

  • Explains that pancreatic enzymes cannot reach the small intestine, so digestion of proteins, fats and carbohydrates suffers (1 mark)
  • States that insulin secretion is already affected because of diabetes (1 mark)
