The Absorptive State: How Your Body Manages Nutrients After a Meal
Explore the vital processes of the absorptive state, where the body efficiently digests food and absorbs nutrients. This article details how insulin regulates glucose, lipids, and amino acids, and their storage in liver, muscle, and adipose cells.
Gluconeogenesis: The Body’s Lifeline for Glucose Production
Explore gluconeogenesis, a vital metabolic pathway that synthesizes glucose from non-carbohydrate precursors, ensuring a steady supply of energy for glucose-dependent organs. This intricate process is essential during fasting or prolonged exercise, playing a critical role in maintaining blood glucose homeostasis.
Decoding Carbohydrate Metabolism: Glycolysis, Krebs Cycle, and ETC
Unravel the complex pathways of carbohydrate metabolism, a fundamental biological process that converts glucose into usable energy for the cell. This article delves into glycolysis, the Krebs cycle, and the electron transport chain, detailing how each stage contributes to the efficient production of ATP.
Homeostatic Regulation of Blood Glucose Levels
Maintaining blood glucose concentration within the optimal range of 70 mg/dL to 110 mg/dL is essential for energy balance and overall health, achieved through a finely tuned homeostatic mechanism. This article explores a diagram illustrating how insulin lowers blood glucose when levels rise and how glucagon increases it when levels drop, providing a clear understanding of this critical physiological process.
Pancreas Anatomy: Structure and Hormone Functions
The pancreas, a versatile organ located in the abdomen, serves both exocrine and endocrine roles, contributing to digestion and blood glucose regulation. This article examines its anatomical structure, including the acinar cells and pancreatic islets, and explores the hormones insulin and glucagon, as revealed in a detailed micrograph at 760x magnification from the University of Michigan Medical School, shedding light on its dual functionality.
