Pramiti Kumari Answered question September 2, 2024
The correct answer is (D) Zn++.
Zinc ions (Zn++) play a crucial role in the crystallization and storage of insulin in the pancreas. Insulin is stored in the form of zinc-insulin crystals in the beta cells of the islets of Langerhans. Zinc helps to stabilize the insulin hexamer, allowing it to crystallize and be stored until it’s released into the bloodstream.
