![]() The seceretory vesicles are stored & when proteins are needed they move to the cell membrane & so proteins are exported.Proteins move from rough ER to the gogli apparatus where they are packaged into secretory vesicles called secretory granules.Present in all cells but larger in those that synthesize & export proteins. ![]() Consists of 5 to 8 membranous sacs usually flattened in structure called cisternae.Matrix contains many enzymes and protein molecules for involved in respiration & formation of ATP.Inner space of cristae – called mitochondrial matrix.Outer membrane is irregular & folded forming shelves – cristae.Also involved in the detoxification of some drugs.Role in the degradation of worn out cytoplasmic organelles like mitochondria.Ribosomes are attached on the surface of ER.Granular or Rough ER A granular or Smooth ER Granular or Rough A granular or Smooth ER. ![]()
