The endoplasmic reticulum (ER) is a network of membranes involved in protein and lipid synthesis, found in all eukaryotic cells. It comes in two forms: rough ER, which is studded with ribosomes and synthesizes proteins, and smooth ER, which is involved in lipid synthesis and detoxification. The sarcoplasmic reticulum (SR), a specialized type of smooth ER found in muscle cells, primarily functions in the storage and regulation of calcium ions, which are crucial for muscle contraction. Thus, while both are types of ER, their functions and locations differ significantly.
The rough endoplasmic reticulum has ribosomes attached to its surface, giving it a "rough" appearance, while the smooth endoplasmic reticulum lacks ribosomes. The rough ER is involved in protein synthesis and processing, while the smooth ER is involved in lipid synthesis and detoxification processes in cells.

Calcium ions in muscle cells are primarily stored in the sarcoplasmic reticulum, a specialized form of the endoplasmic reticulum. When an action potential travels along the muscle cell membrane, it triggers the release of calcium ions from the sarcoplasmic reticulum into the cytoplasm. This influx of calcium ions initiates the contraction process by enabling the interaction between actin and myosin filaments.
The endoplasmic reticulum acts as a highway in the cell, transporting molecules and serving as a network for communication between different parts of the cell. It helps in the synthesis, folding, and transport of proteins and lipids within the cell.
Rough endoplasmic reticulum (RER) is studded with ribosomes, giving it a rough appearance and involved in protein synthesis, while smooth endoplasmic reticulum (SER) lacks ribosomes and is involved in lipid metabolism and detoxification processes. RER plays a major role in the production of secretory and membrane proteins, while SER is involved in the synthesis of lipids and steroid hormones.

The Sarcoplasmic Retiulum releases calcium ions that will cause troponin/tropomyosin complex to move. This exposes the binding sites on actin and allows the cross-bridges of myosin to bind to the actin binding sites.
Im answering my own question and it feels awsome and the answer is yes it does because the ribsomes make the endplasmic reticulum rough and without the ribosomes it is a smooth endoplasmic reticulum. My name is Bob and I like pie.

It's not!!!!! tehee
The endoplasmic reticulum is physically connected to the nucleus through membrane components known as nuclear pores. These pores allow for communication and transport of molecules between the nucleus and the endoplasmic reticulum.
Rough endoplasmic reticulum is studded with protein-producing ribosomes giving it a "rough" appearance, hence its name. It works in concert with the Golgi complex to target new proteins to their proper destinations. The rough endoplasmic reticulum is continuous with both the nuclear envelope and the smooth endoplasmic reticulum. Smooth endoplasmic reticulum has functions in several metabolic processes; it contains enzymes, and it stores calcium ions in muscle cells. Lipid synthesis takes place in the smooth endoplasmic reticulum. The smooth endoplasmic reticulum is continuous with the rough endoplasmic reticulum.
The rough endoplasmic reticulum is rough because of the ribosomes, or the things that make proteins in the cell, are attached to it, making it rough. The smooth one is smooth because their are no ribosomes attached to it.
Endoplasmic reticulum act as a relay station between transportation of materials inside the cell. It have canals where chemicals can pass through. In summary, just like a transportation system. There are rough endoplasmic reticulum as well, which contains spots of Ribosomes on it.
