What is a force beginning with G that pulls something together?
Gravitational force (or gravity) is a force that pulls things together.
Describe the process that cause the muscle to contract?
# When the muscle is in a resting state, thin strands of a protein called tropomyosin are wrapped around the actin filaments, blocking the myosin binding sites. This keeps the myosin from binding to actin. # Molecules called troponin are attached to the tropomyosin. # When calcium is introduced into the muscle cell, calcium ions bind to troponin molecules. # Calcium then pulls troponin, causing tropomyosin to be moved as well, therefore causing the myosin binding sites on the actin to be exposed. # Myosin binds to the now-exposed binding sites. # As soon as the myosin head binds to actin, the head bends at its hinge. # Once the head bends, the myosin loses energy, and remains attached to the actin. # When re-energized by adenosine triphosphate (ATP), the myosin head detaches from the actin filament, and is ready to attach and bend again. # The collective bending of numerous myosin heads (all in the same direction), combine to move the actin molecules closer together. This results in a muscle contraction.
