Document Summary
Cisternae stacked on one another, located near nucleus. Function in protein synthesis and intracellular transportation, transports proteins to golgi. Ser: synth certain lipid & carbs makes membrane for use throughout cell, Break down proteins, food molecules, foreign particles, old organelles. Tay-sachs disease: can"t produce enzyme responsible for lipid- ganglioside breakdown. Breaks down abnormal/misfolded proteins & unnecessary normal proteins, old messages. Tag each molecule with ubiquitin molecule & unfolds it as it enters proteosome, then breaking apart peptide bonds. Parkinson"s disease: proteosome system fails, improperly folded proteins kill nerve cells. Rer and some free, large & small subunit composed of rrna. Nuclear envelope surrounding nucleoplasm has pores allowing proteins in & out. Free ribosomes: make proteins for cell"s domestic use. & base pairs of dna bound around it. Internal supporting framework made of rigid, rodlike pieces. Allows movement of cells, proteins & organelles within cell. Inner & outer layer membranes separated by fluid.
