Answer:
The different skeletal muscle fiber types vary in the speed and duration of their twitches due to -
b) They vary in the rate of hydrolysis of ATP
c) They vary in the removal of Ca+ from the cytosol
Explanation:
There are mainly two types of muscle fibers , i.e.
a) slow twitching, long contraction duration( type I fibers)
b) First twitching but short duration of contraction. ( type II fibers).
Now think of the physiology of muscle. Two components are important, cytosolic Ca++ concentration and Availability of ATP. K+ is related to the action potential ( none or all law, there is no relation to the duration with respect to the potassium). For long contraction muscle fibers need a more steady supply of ATP, and also consistent high concentration of cytosolic Ca++ for muscle contraction to happen. So, these two factor is important for the duration of twitching. So the answer is option f .

Explanation:
Because it is caused by major nerve damage
Capsulitis
It is a permanent deformity that can only be surgically treated. The time it takes to reach the end-stage of capsulitis is different for every patient. It can be a gradual progression over months to years or quicker due to trauma or excessive steroid injections in the area
