Question
Chapter 41.5, Problem 3CC
Summary Introduction
To explain: The effect of insulinomas on blood glucose levels and liver functions.
Introduction:
Insulinomas are cancerous insulin-producing beta cells of pancreatic islets of Langerhans. These tumors lack response to feedback mechanisms and secret insulin even when there is a low blood glucose level in the body.

Insulin's adverse side effects include headache, nau- sea, hunger, confusion and weakness. What can these symptoms be attributed to? Insulin has major effects on muscle and adipose tissue. It increases the rate of glucose transport across the cell membrane, decreases the rate of lipolysis, and increases uptake of triglycerides and some amino acids from the blood. In doing so, what metabolic processes does it favor? Carbohydrates: Lipids: Proteins:arrow_forward

High blood glucose levels are detected by insulin secreting cells of the pancreas initiating a positive feedback loop where insulin secreting cells of the pancreas stimulate the release of insulin into the blood lowering blood glucose levels. Steroids are hormones synthesized from cholesterol. Blood flow in the cardiovascular system is a diffusive process. Paracrine signaling involves exocytosis, diffusion over long distances, and systemic endocytosis in another tissue. At equilibrium d[A]/dt = d[B]/dt = 0 Steroid hormones can bind transcription factors on DNA enhancing transcription.arrow_forward
