Endoplasmic Reticulum (Organelle)

A network of membranes found in eukaryotic cells, involved in protein and lipid synthesis, folding, modification, and transport.

Key Functions:

• Synthesizes proteins (rough ER) and lipids (smooth ER).
• Folds and modifies proteins, ensuring proper structure.
• Transports proteins and lipids to other organelles or for secretion.
• Stores calcium ions.

Interacting Systems & Components:

• Organelle (type of)
• Ribosome (attached to rough ER)
• Golgi Apparatus (interacts with for protein transport)
• Nucleus (continuous with outer membrane)
