The endoplasmic reticulum (ER) is a vital organelle in animal cells, responsible for the synthesis, folding, modification, and transport of proteins and lipids. It consists of two types: the rough ER, which is studded with ribosomes and primarily involved in protein synthesis, and the smooth ER, which is involved in lipid synthesis and detoxification processes. Additionally, the ER plays a crucial role in calcium storage and signaling within the cell. Overall, it contributes significantly to cellular function and homeostasis.
