Complete Question

has an affinity for myosin binding sites in the absence of calcium.

Tropomyosin

Explanation:

Tropomyosin is one of the protein that can be found in the muscles of the body. Tropomyosin is an integral and regulatory protein that is involved in the contraction of the muscles in the body and it prevents the unregulated contraction of the muscles.

In the absence of calcium ions, tropomyosin has an affinity to myosin binding sites. Tropomyosin attaches itself to muscle protein actin and prevents the formation of the cross bridge. This prevents myosin from binding or attaching itself to actin which then results to the prevention of the contraction(shortening and tightening) of the muscles of the body.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
