Endoplasmic Reticulum Flashcards
Endomembrane System
A system of cellular structures, including the endoplasmic reticulum, nuclear envelope, Golgi body, and vesicles, that is used to synthesize and package proteins and lipids
Endoplasmic Reticulum
A cell organelle that assembles and packages proteins and lipids
Lipid
A hydrophobic (water-repelling) biomolecule made up of glycerol and fatty acids; lipids include phospholipids, cholesterol and steroid hormones
Ribosomes
A cell organelle responsible for synthesizing proteins
Rough Endoplasmic Reticulum
A part of the endoplasmic reticulum with ribosomes embedded in it - mainly responsible for assembling and packaging proteins
Smooth Endoplasmic Reticulum
A part of the endoplasmic reticulum responsible for mainly packaging lipids
Vesicle
A small sac surrounded by a membrane which transports cellular products within the endomembrane system.
