2014年10月13日 · However, glycerol makes the membrane permeable to small molecules, including ATP. That means that a glycerinated muscle requires addition of ATP so that the myosin heads can actually bind to the binding sites and create cross-bridges. Magnesium ions aren't required, but they act as catalysts that help the muscle contract more.

As far as I know there are two main reasons for this: promoting a nucleophilic attack; In general, Mg2+ interacts with substrates through inner sphere coordination, stabilising anions or reactive intermediates, also including binding to ATP and activating the molecule to nucleophilic attack ()

Sometimes a small region of my body starts shaking, without any reason and then stops abruptly. Apparently this is a common phenomenon (source: NIH). I researched its cause for a bit and came to k...

2020年3月23日 · The typical text-book illustration of innervation of muscle fibers shows branches at a single position along the fiber. Does any given muscle fiber have more axons that innervate it though, given t...

A myotube is a type of cell which will develop into a muscle fiber. It is formed by the fusion of multiple myoblasts, and thereby acquires multiple cell nuclei.

This is a lab question I cant find the answer in the lab manual or in the text book. What physiological processes in a muscle cause the latent period in a muscle fiber? Please help. Edit: The latent
