Examples

• The cytomembranes of the cell work together to synthesize and transport proteins.
• Eukaryotic cells contain an extensive network of cytomembranes that compartmentalize cellular functions.
• Damage to the cytomembranes can disrupt normal cellular processes.
• The endoplasmic reticulum is one of the most important cytomembranes in protein synthesis.
• Students learned how cytomembranes help organize metabolic pathways in the cell.
