guest lecture matthew fliss Flashcards
1
Q
muscle made of
A
proteins
2
Q
when we grow we increase the amount fo
A
actin and myosin
3
Q
how does our muscle get bigger
A
making more muscle proteins, muscle protein synthesis
- synthesis of new proteins which is actin and myosin
- splitting of myofibrils
- formation of daughter myofibrils
- muscle can only grow a certain amount before splitting
4
Q
myofibrils
A
long filaments that run parralel to each other to form muscle fibres
5
Q
MPS and MPB
A
muscle protein synthesis : growing more actin and myosin
muscle protein breakdown : breaking down myosin and actin
positive NPB allows for muscle growth while
neutral NPB keeps us the same
protein increases MPS after meal
6
Q
eating and training effect on MPS/ MPB
A
spikes MPS and blunts MPB so we have a positive NPB which allows for growth
7
Q
muscle biopsy
A
analyze muscles
8
Q
whats bigger type 1 fibre s or type 2
A
2
