Fibrinogen forms fibrin strands during coagulation. These strands forms a network and the meshes of which are occupied by blood cells, this structure finally forms a clot.
Antibodies are derived from - Globulin fraction of plasma proteins which means globulins are involved in defence mechanisms.
Albumin is a plasma protein mainly responsible for BCOP.

Calcium is important in skeletal muscle contraction because it
Binds to troponin to remove the masking of active sites on actin for myosin.
Activates the myosin ATPase by binding to it.
Prevents the formation of bonds between the myosin cross bridges and the actin filament.
Detaches the myosin head from the actin filament.
