Week Five (Part One) Flashcards
Blood Glucose
Primary organs involved:
Liver and pancreas
Blood Glucose
Organ relying exclusively on glucose for energy:
CNS
Blood Glucose
Sources of CHO (Absorbed from Diet)
Energy
Glycolysis
Blood Glucose
Sources of CHO (Absorbed from Diet)
Stored as Glycogen
Glycogenesis
Blood Glucose
Sources of CHO (Absorbed from Diet)
Other
Transformed into fat
Hormonal Regulation
Hormones Involved:
Insulin Glucagon Catecholamines Growth Hormone Glucocorticoid
Hormonal Regulation
Insulin (Function and Regulation):
Lowers blood sugar; regulated by blood sugar concentration.
Hormonal Regulation
Insulin (Metabolism):
Destroyed by liver and kidney
Hormonal Regulation
Insulin
Mechanism (Pathology):
Promotes glucose uptake by the cells by activating the glucose transport system.
Inhibits gluconeogenesis
Increases protein syntesis
Promotes fate synthesis from glucose
Hormonal Regulation
Glucagon (Function and Regulation):
Increases blood sugar; regulated by blood sugar concentration.
Hormonal Regulation
Glucagon (Metabolism):
Metabolized in the liver
Hormonal Regulation
Glucagon
Mechanism (Pathology):
Opposite to insulin.
Promotes glucogenolysis
Promotes gluconeogenesis
Promotes lipolysis (the breaking down of ketone bodies)
Promotes the breaking down of protein
Hormonal Regulation
Catecholamines- Epinephrine/Norepinephrine (Function and Regulation):
Increases blood sugar in; regulated by stress.
Hormonal Regulation
Catecholamines- Epinephrine/Norepinephrine
Mechanism (Pathology):
Inhibit insulin release
Promote glycogenolysis
Mobilize fatty acids from adipose tissue
Hormonal Regulation
Growth Hormone (Function and Regulation):
Inhibited by insulin and high blood sugar; increased by low insulin, low blood sugar, and stress
