Metabolic fuels(fed vs fasting State)

Описание: GLUCOSE METABOLISM – COMPLETE & CLINICALLY EXPLAINED (PHYSIOLOGY + BIOCHEMISTRY)
This lecture series provides a complete, structured, and in-depth explanation of glucose metabolism, designed for MBBS, medical, nursing, and health science students who want real understanding, not memorization.
Glucose metabolism explains how the body absorbs, stores, releases, and utilizes glucose under different physiological and pathological conditions. In this series, complex pathways are simplified and linked to clinical relevance, making learning easier and retention stronger.
🔬 WHAT THIS SERIES COVERS (STEP BY STEP)
1️⃣ Introduction to Glucose Metabolism
• Importance of glucose as the main energy source
• Why the brain and RBCs depend on glucose
• Concept of metabolic homeostasis
2️⃣ Digestion, Absorption & Transport
• Breakdown of dietary carbohydrates
• Intestinal absorption of glucose
• Role of insulin in cellular uptake
3️⃣ Fed (Absorptive) State
• Rise in blood glucose after meals
• Insulin secretion and its actions
• Shift toward storage and energy use
4️⃣ Glycogenesis (Simplified)
• Conversion of excess glucose to glycogen
• Liver vs muscle glycogen storage
• Why the liver maintains blood glucose
5️⃣ Fasting State vs Fed State
• Hormonal changes (insulin vs glucagon)
• Metabolic priorities during fasting
• Clear side-by-side comparison
6️⃣ Glycogenolysis
• Breakdown of glycogen during low glucose
• Role of liver in maintaining blood sugar
• Why muscle glycogen cannot raise blood glucose
7️⃣ Glycolysis
• ATP production from glucose
• Aerobic vs anaerobic pathways
• Importance in RBCs and exercising muscle
8️⃣ Gluconeogenesis
• Formation of glucose from non-carbohydrate sources
• Role of liver and kidney
• Importance during prolonged fasting
9️⃣ Starvation & Metabolic Adaptation
• Shift from glucose to fat and ketones
• Protein sparing mechanisms
• Survival physiology
🔟 Water Balance & Energy Requirement
• Daily water intake and output
• Relationship between glucose and hydration
• Minimum daily energy requirement
1️⃣1️⃣ Lifestyle & Metabolic Effects
• Constant eating without fasting
• Physical inactivity and insulin resistance
• Long-term metabolic consequences
1️⃣2️⃣ Diabetes Mellitus (Metabolic View)
• Why hyperglycemia occurs
• Polyuria, polydipsia, polyphagia explained
• Clinical relevance of glucose dysregulation
🎓 WHO THIS IS FOR
