* Ribosomes: These are the sites of protein synthesis. They read the genetic code from messenger RNA (mRNA) and use it to assemble amino acids into polypeptide chains.
* Endoplasmic Reticulum (ER): This is a network of interconnected membranes that plays a crucial role in protein folding, modification, and transport. There are two types of ER:
* Rough ER: Ribosomes are attached to its surface, giving it a "rough" appearance. It is involved in protein synthesis and initial folding.
* Smooth ER: Lacks ribosomes and is involved in lipid synthesis, detoxification, and calcium storage.
* Golgi Apparatus: This organelle processes and packages proteins for secretion or delivery to other organelles. It modifies proteins, adds carbohydrates, and sorts them into vesicles for transport.
These organelles work together in a complex and coordinated manner to ensure the efficient synthesis, processing, and delivery of proteins that are essential for cellular function.
