The Endomembrane System and Proteins

Vesicles and vacuoles are membrane-bound sacs that function in storage and transport.

The endoplasmic reticulum is an organelle that is responsible for the synthesis of lipids and the modification of proteins.

The Golgi apparatus sorts and packages materials before they leave the cell to ensure they arrive at the proper destination.

Lysosomes are organelles that digest macromolecules, repair cell membranes, and respond to foreign substances entering the cell.

Peroxisomes neutralize harmful toxins and carry out lipid metabolism and oxidation reactions that break down fatty acids and amino acids.
