To determine: The way by which the glucose concentration affects the insulin secretion of cells.
Introduction: Diabetes mellitus is a condition in the body that leads to
There are many foreign substances that act like activators and inhibitor molecules, which disrupt normal hormonal activities. One such chemical is Bisphenol A (BPA) that acts like natural estrogen hormone and have an endocrine disrupting and diabetogenic activity.

Explanation of Solution
BPA is a synthetic compound present in epoxy resins and plastics, such as food containers, beverage bottles, and so on. Using different studies, the researchers have found that BPA directly acts on the pancreatic cells and increases the risk of type 2 diabetes mellitus. BPA activates the estrogen receptor that presents in the pancreatic cells and disrupts the insulin secretion Diarylpropionitrile (DPN), which is a chemical that has similar effects as BPA. It can also bind and activate the estrogen receptor as BPA and affect the insulin secretion.
Refer Figure 34.11 “Effects of BPA and DPN on glucose-stimulated insulin secretion” in the textbook. In the given experiment, researchers focused to determine the effects of BPA on insulin secretion. The human pancreatic cells were cultured and treated with BPA and DPN. Later, the cells were monitored for the insulin secretion. The cells that were exposed to glucose alone, without the treatment with BPA and DPN, secreted less insulin when compared to the treated ones. DPN treated pancreatic cells produced two times more than the insulin and those cells with BPA treatment secreted three times more than the insulin than that of the cells that were exposed to glucose alone.
BPA treated pancreatic cells produced three times more than the insulin, DPN treated cells secreted two times more than the insulin when compared to the cells that were only exposed to glucose.

- A 25-year-old woman presents to the emergency department with a 2-day history of fever, chills, severe headache, and confusion. She recently returned from a trip to sub-Saharan Africa, where she did not take malaria prophylaxis. On examination, she is febrile (39.8°C/103.6°F) and hypotensive. Laboratory studies reveal hemoglobin of 8.0 g/dL, platelet count of 50,000/μL, and evidence of hemoglobinuria. A peripheral blood smear shows ring forms and banana-shaped gametocytes.
