Question
An 80 kg man who has poor kidney function, but not on dialysis, needs this much protein in his diet:
A. 40-48 g protein/day
B. 48-64 g protein/day
C. 80-96 g protein/day
D. 96-112 g protein/day
The roles of CCK and Secretin produced by the duodenum in response to dietary protein includes all these, except:
A. Stimulate pancreas to release digestive enzymes
B. Stumulate gall bladder to release bile
C. Stimulate faster stomach emptying
Which of the following is NOT true about distribution of amino acids?
A. After absorption from the duodenum, amino acids immediately enter the systemic circulation
B. Liver completes most deamination and transamination reactions
C. Uptake of amino acids into cells requires insulin
D. Amino acide absorption into the blood causes pancreas to release insulin
E. All of the above are true
Which of the following is NOT true about cellular metabiolism of amino acids?
A. Excess amino acids get stored for later
B. Ammonia is converted to urea by the liver
C. Urea is excreted by the kidneys
D. Ammonia is not an excretable waste molecule
Explanation / Answer
An 80 kg man who has poor kidney function, but not on dialysis, needs this much protein in his diet:
A. 40-48 g protein/day
B. 48-64 g protein/day ( 0.6-0.8 g/kg)
C. 80-96 g protein/day
D. 96-112 g protein/day
The roles of CCK and Secretin produced by the duodenum in response to dietary protein includes all these, except:
A. Stimulate pancreas to release digestive enzymes
B. Stumulate gall bladder to release bile
C. Stimulate faster stomach emptying (inhibits emptying)
Which of the following is NOT true about distribution of amino acids?
A. After absorption from the duodenum, amino acids immediately enter the systemic circulation
B. Liver completes most deamination and transamination reactions
C. Uptake of amino acids into cells requires insulin
D. Amino acide absorption into the blood causes pancreas to release insulin (Glucose absorpption stimulates insulin secretion_)
E. All of the above are true
Which of the following is NOT true about cellular metabiolism of amino acids?
A. Excess amino acids get stored for later ( aminoacids cannot be stored, is excreted as urea)
B. Ammonia is converted to urea by the liver
C. Urea is excreted by the kidneys
D. Ammonia is not an excretable waste molecule
