What is the primary function of the endoplasmic reticulum?
Protein and lipid synthesis
Which organelle is composed of a network of membranes for protein and lipid synthesis?
Endoplasmic reticulum
What type of proteins does the rough endoplasmic reticulum synthesize?
Membrane-bound proteins
Which organelle is responsible for synthesizing transmembrane proteins destined for organelles or secretion?
Ribosomes
What is the primary role of the Golgi apparatus?
Protein modification and packaging
Which organelle has two different appearances and is involved in synthesizing transmembrane proteins?
Endoplasmic reticulum
Learn about the smooth endoplasmic reticulum, which is the portion of the endoplasmic reticulum that lacks ribosomes, and its role in lipid production and detoxification. Explore the Golgi apparatus, an organelle that modifies and sorts proteins and lipids derived from the endoplasmic reticulum.
