Serum creatinine - correct answer Produced due to protein and muscle breakdown Serum creatinine - correct answer This will be elevated in the event of kidney disease. Kidney function loss has to be at least 50%. BUN - correct answer Blood urea nitrogen. Results from breakdown of protein in the liver BUN - correct answer Factors that affect this are: - dehydration - infection - chemotherapy - steroid therapy - reabsorption of blood in the liver from damaged tissue Urinalysis - co...

What is a glucogenic amino acid? correct answers - amino acids that are catabolized to pyruvate or an intermediate of the TCA cycle - can be used for glucose synthesis What is a ketogenic amino acid? correct answers - amino acids that are catabolized to acetyl CoA or acetoacetate - cannot give rise to the net synthesis of glucose but rather lead to the formation of fatty acids, ketone bodies, or their precursors Which amino acids are exclusively ketogenic? correct answers - leucine - ly...

Type 1 diabetes characterized by a destruction of pancreatic beta cells; these patients no longer have the ability to produce insulin - typically diagnosed before age 30 Diabetic ketoacidosis acidity of the blood caused by the presence of ketone bodies produced when the body is unable to burn sugar Manifestations: - polyuria - polydipsia - N/V - fatigue - fruity breath - blurry vision - Kussmaul's respirations Type 2 diabetes common in those over 30 with obesity Typically stems from insulin ...
