landslides are due to different forces of attraction that act on the fibers, basically of an electrostatic nature due to varied currents of ions such as calcium and potassium. Also they act mechanical and chemical forces in the muscular contraction, since it is necessary the ATP that as we know is the molecule that gives energy to the muscular cell. The contraction can be of two types: Isometric contraction, the muscle length remains unchanged but a position is maintained. Isotonic contraction: the muscle is shortened to allow movement. Transport function The organism uses proteins so that nutrients and other substances reach the interior of the cell. To do this they must go through different means, for example a fat-soluble vitamin (hydrophobic) such as vitamin E, it must be transported through an aqueous medium.
