Pancreas has two types of cells namely islets of Langerhans and acinar cells. In the early years of research on diabetes, extract of this gland was tested on diabetic patients. Resutls are tabulated below. (i) Extract of pancereas -
(ii) Islet cell extract +
(iii) Acinar cell extract -
The correct interpretation is that

Options

A. anti-diabetic factor in extract'C' was inactivated by extract 'A'
B. anti-diabetic factor present in 'A' was destroyed by 'B'
C. both 'A' and 'C' destoyed the anti=diabetic factor present in 'B'
D. anti diabetic factor present in 'B' was destroyed by

Answer

D

Explanation

The result shows that the extract of pancereas is ineffective to reduce blood sugar level. The extract contains secretions of both exocrine and endocrine part i.e., acinar cells and iselt of Langerhans respectively Since extract of endocrine part which is islet of Langerhans is individually capable of reducing sugar level, this shows that some factors from acinar cells are preventing anti-factor from acinar cells are preventing anti-diabetic factor to function.
