NUT 10 Lecture Notes - Lecture 2: Blood Sugar, Beta Cell, Lipoprotein
Document Summary
Body store glucose in the form of glycogen. Need hormone insulin for glucose to enter cells ( get permission from cell receptor) Glucose accumulates in the bloodstream and damages blood vessel walls which leads to poor circulation, heart disease, loss of eyesight. Type 2 diabetes: insulin does not work effectively (cell receptor does not hear insulin knocking-- faulty insulin receptors) Messes up cell walls, binds to proteins that it shouldn"t bind to. Leads to cardiovascular disease, poor circulation (amputation), loss of. Change diet so no need much insulin. Smaller meals, increase in protein and fat. Liver: stores - of total carbs, fuel brain and cns/pns. If levels below normal: pancreas sends hormone signal to liver to release glucose units from its stored glycogen. Glucose can be broken down without oxygen for energy to fuel your brain. Still some potential energy in three carbons (change from c3 to c2) Energy (4 kcal/ g of carbohydrate) + co2 + h2o)
