Answer:</h2>
<u>A. The concentration of calcium in the myofibril must decrease.
</u>
<h2>
Explanation:</h2>
Each time we move a muscle, it requires the joined activity of trillions of myosin engines. Our muscle cells use calcium particles to facilitate this monstrous atomic exertion. At the point when a muscle cell is given the sign to contract from its related nerves, it discharges a surge of calcium particles from an uncommon intracellular holder, the sarcoplasmic reticulum that encompasses the groups of actin and myosin fibers.
The calcium particles quickly spread and tie to Tropomyosin on the actin fibers. They move shape somewhat and enable myosin to tie and start moving up the fiber. These trillions of myosin engines will keep climbing, getting the muscle, until the calcium is evacuated.
The calcium pump enables muscles to relax after this furious flood of calcium-instigated constriction. The siphon is found in the film of the sarcoplasmic reticulum.
I think the answer is "It's tightly packed cells allow for protection against harmful substances."

Explanation:
The level of protein X in these patients will be low due to degradation in the proteasome. Ubiquitnation process occur when ubiquitin is attached to a particular protein and the protein become deactivated. Ubiquitin is a small biochemical molecule which marks out proteins for destruction. Any protein that have ubiquitin attached to it will be transported to the proteasome for destruction by degradation.
