Q
Major pathways for forming ATP
A
Cells that rely mostly on on the oxygen using aerobic pathways for ATP generation are OXIDATIVE FIBERS, those that rely more on anaerobic glycolysis are GLYCOLYTIC FIBERS.
1
Q
Speed of contraction
A
Slow fibers and fast fibers. Difference in speed reflects how fast their myosin ATPase split ATP, and on the pattern of electrical activity of their motor neurons.

Q
Load
A
Because muscles are attached to bones, they are always pitted against some resistance, or load, when they contract
