They carry an electric charge
Answer:
B
Explanation:
Amino acids have a basic skeleton as shown in the illustration.An alpha carbon bonded to a carboxyl gorup, amino grpup, hydrogen, and a side chain. However, amino acids differ in their side chains. These side chains can give different amino acids different properties because of their different properties. The side chains give different properties to the amino acid such as size, shape, ionization properties, polarity, charge, acidity, and basicity.

Answer:
Tropomysin, calcium
Explanation:
Tropomysin is a protein that prevents muscle contraction hence acts as a contraction inhibitor. It wraps around the actin blocking the binding sites for myosin on the actin.
Muscle will only contract when they get a rush of calcium ions.
The calcium ions binds to troponin, the troponin changes its shape. The change in shape will remove tropomyosin from the binding sites allowing myosin to bind on the actin leading to muscle contraction.
