protein 2

Question 1

what is muscle protein synthesis?

Answer 1

amino acids synthesized into protein

Question 2

what is muscle protein balance?

Answer 2

balance btw synthesis and breakdown

Question 3

protein synthesis - protein breakdown = net protein balance

Answer 3

PB> PS - balance protein loss

PS> PB + balance protein gain

Question 4

what is net muscle protein synthesis ?

Answer 4

+ net muscle protein balance

either increased protein synthesis or decreased protein breakdown

Question 5

what is amino acid breakdown ?

Answer 5

amino acids taken up from blood into a tissue - indication of net muscle protein synthesis

Question 6

what is amino acid utilization ?

Answer 6

use of amino acids from ingested sources for building proteins

Question 7

muscle protein synthesis

Answer 7

all within intracellular amino acid pool
endogenous aa
aa from ingested proteins

Question 8

exogenous aa stimulate muscle protein at rest

Answer 8

yup

Question 9

how do we achieve the maximal stimulation of muscle protein synthesis?

Answer 9

exercise + AA

exercise alone is not enough fro + net muscle protein synthesis

Question 10

how is muscle mass gradually increased ?

Answer 10

nutrient consumption following exercise stimulates muscle protein synthesis and inhibits exercise induced rise in protein breakdown

Question 11

how does insulin increase net balance ?

Answer 11

by ameliorating the increase in breakdown following resistance exercise

Question 12

aa + insulin = optimised muscle protein balance

Answer 12

yup
