📋 3️⃣ Memory Tables
Table 1 — Fed State vs Fasting State
| Feature | Fed State | Fasting State |
|---|---|---|
| Main Hormone | Insulin | Glucagon |
| Blood Glucose | High | Low |
| Major Pathway | Glycogenesis | Glycogenolysis |
| Liver Function | Stores glucose | Releases glucose |
| Energy State | Storage | Mobilization |
Table 2 — Liver vs Muscle Glycogen
| Feature | Liver Glycogen | Muscle Glycogen |
|---|---|---|
| Main Purpose | Maintain blood glucose | Muscle contraction |
| Glucose-6-Phosphatase | Present | Absent |
| Can Release Free Glucose | Yes | No |
| Main Hormonal Control | Glucagon | Adrenaline |
⚡ 4️⃣ Rapid Revision Points
Must Remember:
• Liver maintains blood glucose homeostasis.
• Glycolysis produces ATP from glucose.
• Gluconeogenesis maintains glucose during prolonged fasting.
• Glycogenesis occurs mainly in fed state.
• Glycogenolysis increases during fasting.
• Insulin lowers blood glucose.
• Glucagon raises blood glucose.
• Muscle glycogen cannot directly increase blood glucose.
• RBCs depend entirely on anaerobic glycolysis.
• Brain is highly sensitive to hypoglycemia.
• GLUT-4 is insulin dependent.
• Adrenaline stimulates glycogen breakdown during stress.
🩺 5️⃣ Clinical Memory Hooks
Clinical Hook:
Diabetes Mellitus → Insulin deficiency → Hyperglycemia.
Clinical Hook:
Pyruvate kinase deficiency → Reduced RBC ATP → Hemolytic anemia.
Clinical Hook:
Liver disease → Impaired gluconeogenesis → Fasting hypoglycemia.
Clinical Hook:
Excess insulin → Neuroglycopenia → Sweating and confusion.
Clinical Hook:
Glycogen storage disease → Defective glycogen breakdown → Hepatomegaly and hypoglycemia.
6️⃣ Do’s, Don’ts & ⚠️ Common Mistakes
✅ Do’s
• Do relate pathways to fed and fasting states.
• Do remember liver is the main glucose-regulating organ.
• Do connect hormones with their metabolic effects.
• Do compare liver glycogen with muscle glycogen.
• Do understand why RBCs depend on glycolysis only.
❌ Don’ts
• Don’t confuse glycogenesis with glycogenolysis.
• Don’t assume muscle releases glucose into blood.
• Don’t associate insulin with fasting pathways.
• Don’t forget reciprocal regulation of glycolysis and gluconeogenesis.
• Don’t confuse glucagon effects with adrenaline effects.
⚠️ Common Mistakes
• Confusing gluconeogenesis with glycogenolysis.
• Forgetting that RBCs lack mitochondria.
• Thinking brain stores significant glycogen.
• Assuming glycogenesis occurs during fasting.
• Forgetting glucose-6-phosphatase is absent in muscle.
