muscle fibres Flashcards
1
Q
contractile speed
A
speed at which fibres contract
2
Q
mitochondria
A
Powerhouse of the cell, provides large amounts of energy using O2
3
Q
cappilaries
A
provides blood to muscles, site of gas exchange (O2 and CO2)
3
Q
myoglobin
A
02 carrier in muscle fibre (strong attraction to 02)
4
Q
aerobic
A
produces energy with the presence of o2
4
Q
colour
A
related to myoglobin - more myogloblin = more red in colour = more o2 present in cell
5
Q
anaerobic
A
produces energy without the presence of o2
6
Q
oxidative capacity
A
muscles ability to work aerobicly with o2
7
Q
glygotic capacity
A
muscles ability to work anerobicly without o2
