Why do Diabetics have sweet breath?
B/c they are undergoing ketoacidosis and as result of the ketoacidosis and acetone.
Why do diabetics breakdown fat alot for NRG?
B/c their cells cant get glucose for NRG so they breakdown fat for NRG.
production of fat from glucose or AA

These AA in the blood and cells must be used with a _______ or so.
What are the (5) function of protein?
1 - Make up all enzymes and antibodies

2 - in plasma proteins responsible for agglutination

3 - in actin and mysin that make up muscle proteins

NH3, ammonia
NH3 or ammonia are quickly converted to _________ ?
Urea goes into ______ then to _______ and put into _______ and excreted.
blood, kidney, urine
AA can be converted to ________, __________, or various acids of Krebs cycle.
glucose, fatty acids
What controls varous fx of metabolism?
What is endocrine system?
System of glands that secrete hormones into blood, travel thru circulatory system and have effect on certain bodily functions
What is normal glucose level?
What 2 hormones control glucose level in blood?
Insulin and Glucagon
What organ makes insulin?
Beta cells of pancreas
What does insulin do if blood sugar is too high?
Make cells absorb more glucose from the blood.
When isulin allows cells to absorb excess glucose what is this excess glucose converted to?
Fat or glycogen
What affect does insulin have on gluconeogenesis?
Inhibits production of glucose from fat and protein. This is bad
Diabetics want to limit carbs and sugar in diet to stabilize their __________? This way glucose is made slowly from __________ of fatss and proteins and insulin need is decreased.
