Document Summary
Area outside of nucleolus is called the nucleoplasm. Outer membrane - connected to the endoplasmic reticulum (er) Protein synthesis takes place here, for proteins to be exported, or put into membrane. Synthesis of proteins need to be kept away from cytoplasm (digestive enzymes) Various modification of proteins take place in rough er. Ribosomes bound to rer are not a stable part of the rer. Ribosome binds to rer when it is translating a protein is destined for secretion - contains signal peptide. Membranes of the nucleus, er, golgi, and lysosomes form a network. Connected by vesicles which are carried by motor proteins, along cytoskeletal tracks. for transport. Combines with phagosome to break up intaken product to be used in the inside the cell. After the product is broken up, the useful monomers and dimers are released into the cell and the waste is excreted out of the cell. Vesicles fuse with primary lysosome -> 2nd lysosome.
