Question

Quizplus · Accepted Answer

Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels by facilitating the uptake of glucose into cells for energy production or storage. When blood sugar levels rise (e.g. after eating), insulin is released to reduce them and prevent damage to organs and tissues. Without sufficient insulin, the body cannot use glucose effectively, leading to high blood sugar levels (hyperglycemia) and, over time, various complications such as diabetes, heart disease, nerve damage, and blindness.
