Presentation Transcript

  1. Rough Endoplasmic reticulum – the structure • The basic structure consists of sheets of phospholipid membrane, which ribosome's are attached to. • Made up of a series of thin, intricate channels, and exists in the folds in the phospholipid membrane. • Many ribosome's are attached to endoplasmic reticulum. These are small dense organelles, about 20nm in diameter. • It also contains Cytosol, which is a solution containing enzymes.

  2. Rough Endoplasmic reticulum – the functions • The narrow fluid-filled space between the membranes acts as a transport network which moves materials around the cell. • The folded membrane of ER creates a large surface area. • Ribosome's are the part of the RER which carry out protein synthesis. This is where RNA (produced by the nucleolus) binds to a ribosome, which uses the information encoded in the RNA to assemble amino acids in the correct order to produce the desired protein. • The protein produce in RER is exported from the cell for use elsewhere
