Glycogenesis:   This  is an anabolic process  in which  glucose is polymerized  into glycogen by the   sequence of  reactions.  Since glycogenesis occur  in all  body  cells .but  its main  sites are liver  and skeletal muscles. Liver  and muscle cells  remove excess  glucose from  blood  and polymerize  it into  glycogen  for  storage .About  400 grams   of storage glycogen is normally  found  in human  body.
