A combination of downward pressure AND friction. It occurs at the deeper layers of tissue resulting in cell deformation and cell death
Answer:
Calcium is important element in the process of the muscle contraction. In the absence of calcium, the myosin head is covered by tropomyosin and no muscle contraction occur.
The presence of calcium ion increases the actin and myosin bridging by the removal of tropomyosin. This process is energy dependent and requires ATP for its continuation. The intake of caffeine increase the calcium level and results in the ease in musce contraction. This calcium elevation do not have the ability to elevate the lipase and protease ads this activation requires specific messengers.
