  • Glucose 6-phosphatase activity and ribonucleic acid, which are localized predominantly in the rough endoplasmic reticulum, were increased. (portlandpress.com)
  • Besides, the smooth ER also contains the enzyme's glucose-6-phosphate that is important for the conversion of glycogen to glucose. (microbenotes.com)
  • reticulum is used to breakdown glycogen to glucose. (ronl.org)
  • The SER has a smooth surface, which is free of ribosomes and is specialized for the synthesis and storage of lipids and other substances. (differencesfinder.com)
  • Function: Rough endoplasmic reticula are involved in the synthesis of proteins. (vidque.com)
  • The endoplasmic reticulum (ER) serves important functions particularly in the synthesis, folding, modification, and transport of proteins. (vidque.com)
  • The outer ( cytosolic ) face of the rough endoplasmic reticulum is studded with ribosomes that are the sites of protein synthesis . (ipfs.io)
