10 Questions
Which hormone promotes gluconeogenesis, amino acid uptake by the liver, ureagenesis, and protein catabolism?
Glucagon
What is the primary effect of cortisol on skeletal muscle and hepatic use of amino acids?
Enhances skeletal muscle catabolism and promotes hepatic use of amino acids for gluconeogenesis
What is the source of energy for skeletal muscle during increased energy production after injury or sepsis?
Branched-chain amino acids (BCAAs)
What is the primary impact of metabolic stress on the use of carbohydrate, protein, fat, and oxygen?
Increased flow of substrate but poor use of carbohydrate, protein, fat, and oxygen
Which hormones play a role in the accelerated proteolysis after injury and sepsis?
Counterregulatory hormones
What is the primary role of counterregulatory hormones in the context of injury and sepsis?
Promote accelerated proteolysis
How does glucagon primarily affect amino acids in the liver?
Promotes amino acid uptake by the liver
What is the main impact of cortisol on skeletal muscle and hepatic amino acid utilization?
Enhances skeletal muscle catabolism and promotes hepatic use of amino acids
What is the primary source of energy for skeletal muscle during increased energy production after injury or sepsis?
Branched-chain amino acids (BCAAs)
What is the main effect of metabolic stress on energy production and substrate utilization?
Energy production increasingly depends on protein
