Heat is a product. B. H,0 is a product E. CO, is a productExplanation / Answer
15.
A. It is needed make creatinine phosphate.
In the process of contraction starting from release of calcium out of the sarcoplasmic reticulum all the given options require ATP except Option A
16.
C. The time takes for calcium to be released.
Latent period between the action potential and muscle contraction describe the interval or time taken to release of calcium out of the sarcoplasmic reticulum.
It takes around 3-10 seconds
17.
A. muscle spasm
Muscle spasm which means the involuntary contraction of muscle due to stimulus from the spine when it is injured. It is associated with pain.
Where as
Muscle strain is the muscle injury which produces severe pain.
Muscle tone is the partial contraction of muscle or muscle tension exerted at rest.
Muscle fatigue means muscle losses it ability to produce stimulus or tonicity.
18.
C. Increasing the stimulus upto the Maximal stimulus.
