Question
Chapter 1, Problem 31RQ
Summary Introduction
To determine:
The effect of insulin on the blood glucose level, if insulin hormone is controlled by a negative feedback mechanism. The hormone is released, when there are increased levels glucose in the blood.
Introduction:
Negative feedback is referred as a type of regulation, where the end product of any procedure reduces the stimulus of the procedure. Thus, the body consists of its internal controller mechanisms to maintain the body's pH, temperature, blood sugar, hormones and many other things. Insulin is a pancreatic hormone.

In the answer, discuss insulin and glucagon. (You do not need to talk about the other hormones that influence glucose levels when stress levels are high.) For each hormone, state the stimuli that causes secretion, the cell that secretes the hormone, the metabolic pathways stimulated by the hormone and the overall effect of each hormone.
Chronic stress or GC exposure can cause insulin resistance. The influence of GC on insulin is complex, but leads to hyperinsulinemia (high circulating insulin levels) and insulin resistance. Insulin resistance is typically caused by a decreased number of insulin receptors on the cell surface. Speculate on a mechanism resulting in a decreased number of insulin receptors.
A group of students are participating in a 24-hour fast to raise money for the foodbank. Fasting refers to refraining from eating for a period of time. Select the answer that describes how the students’ bodies would respond to maintain homeostasis.
Select one:
a. The beta cells of the islets of Langerhans are producing glucagon to decrease blood glucose levels.
b. The alpha cells of the islets of Langerhans are producing insulin to increase blood sugar levels.
c. The alpha cells of the islets of Langerhans are producing glucagon to increase blood glucose levels.
d. The beta cells of the islets of Langerhans are producing insulin to decrease blood sugar levels.
