Document Summary
#1 feature in eukaryotes that allows them to have organelles; endomembrane system on the outside creating a barrier, and an intracellular set of membranes forming compartments. Subcellular compartments within the cytosol surrounded by a membrane. Their functions are varied, and depend on the cell"s role. Nucleolus: rna to build ribosomes is located here. Conversion from mrna to protein in the ribosomes. Ribosomes have 2 subunits that accommodate trna (carry amino acids) Subunits made up of sections of proteins; not 2 large proteins intertwined. Translation can occur on the er or in the cytoplasm. Smooth er: backdoor that can get rid of toxins in the cell, lipid synthesis, smooth because membrane is smooth. Rough er: studded w/ a lot ribosomes that can carry out translation at the same time, post-translation maturation, starts off as an extension of the nuclear membrane, and forms a network in the cytoplasm. Digestive enzyme in the cytosol or cytoskeleton proteins)
