The formation of many cell-cell adhesions entails two types of molecular interactions:

1. Trans binding interactions 

2. Cis binding interactions

The rate of sedimentation is dependent upon the applied centrifugal field (cm s-2), G,

that is determined by the radial distance, r, of the particle from the axis of rotation (in cm)

and the square of the angular velocity ω, of the rotor (in radians per second):

In skeletal muscle cells, 

a low cytosolic Ca+2 level is maintained by a unique Ca+2 ATPase that continually pumps Ca+2 ions from

the cytosol containing the myofibrils into the SR, establishes a reservoir of Ca+2 in the SR.
