Q

slow twitch

A

contract slowly
for posture e.g. back muscles

for endurance
work for a long time without fatigue

energy released slowly through aerobic respiration
lots of mitochondria and blood vessels so rich supply of oxygen

lots of myoglobin so reddish in colour

29
Q

fast twitch

A

contract very quickly
for fast movement e.g. eyes and leg

short bursts of speed e.g. sprinting
fatigue quickly

energy released quickly through anaerobic respiration using glycogen (stored glucose)
few mitochondria or blood vessels

not much myoglobin so whitish/pale red

30
Q

myoglobin

A

a red-pigmented protein that stores oxygen
