Homeostasis: Blood Glucose 90mg/ 100mL or 5.6-3.9 mmolL-1, Benji -…
Homeostasis: Blood Glucose 90mg/
100mL or 5.6-3.9 mmolL-1
Low Blood Glucose Level (Stimulus: skipping a meal)
Hypoglycemia (below 3.9mmolL-1)
Glycogenolysis
Gluconeogenesis
Alpha cells of pancreas stimulated to release glucagon into
the blood
hormone glucagon stimulates glycogen
Glycogen is broken down by liver and glucose is synthesised
Negative feedback slows hormone secretion
blood glucose level is restored
Glycogen is created from glucose by the liver and skeletal muscles cels along with being stored there
Glycogenesis
High Blood Glucose level (stimulus: eating a high carbohydrate loaded meal)
Hyperglycemia
Glycogenisis
Excess glucose converted into glycogen
Beta cells of pancreas to stimulate release of insulin into the blood
Insulin Hormone
Body cells take up more glucose
Blood glucose levels decline to a set point and stimulus for insulin decreases
Blood glucose level is restored
Diabetics of Type 1 diabetes body's immune system destroys the insulin-producing beta cells in the pancreas.
Respriation Equation relation:
Glucose is a component of the equation
Homeostasis controls whether there is enough for respiration

Type 2 diabetes is when the pancreas doesn't produce enough insulin, or the cells become resistant to the insulin that it produces which prevents it from working properly to allow glucose into cells for energy.
