What does the smooth endoplasmic reticulum remind you of?
The smooth endoplasmic reticulum (SER) reminds me of a vast network of highways, where various cellular processes take place. Just as highways facilitate the transport of goods and services, the SER is involved in lipid synthesis, detoxification, and calcium ion storage. Its smooth, tubular structure contrasts with the rough endoplasmic reticulum, which is studded with ribosomes, similar to how some highways may have bustling service areas while others remain quiet and streamlined.
What synthesizes proteinspackages proteins for transport and stores calcium ions?
The endoplasmic reticulum (ER) is the organelle that synthesizes proteins, packages them for transport, and stores calcium ions. The rough ER, studded with ribosomes, is primarily involved in protein synthesis, while the smooth ER plays a key role in calcium ion storage and lipid synthesis. Together, these structures facilitate the production and distribution of proteins within the cell.
What does Endoplasmic Reticulum need to live?
The endoplasmic reticulum is a vital organelle within a cell that requires nutrients, energy, and proper cellular conditions to function and survive. It relies on a constant supply of proteins, lipids, and other molecules that it helps to synthesize and transport within the cell. Additionally, it needs a stable environment with the right pH, temperature, and ion concentrations to carry out its functions effectively.
Where in the treated cells is CFTR actually produced?
In treated cells, CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) is produced primarily in the endoplasmic reticulum (ER) and then transported to the plasma membrane. The CFTR protein undergoes post-translational modifications in the ER and Golgi apparatus before being folded correctly and sent to the cell surface, where it functions as a chloride channel. Proper trafficking and expression at the plasma membrane are crucial for its function in regulating ion transport.
What channel is ion on optimum?
On Optimum, the ION Television channel is typically found on channel 57. However, channel numbers can vary based on your specific location or package. It's always a good idea to check your local channel lineup or the Optimum website for the most accurate information.
What part of the cell stores calcium ion?
the smooth endoplasmic reticulum
Does the smooth er transport proteins?
The smooth endoplasmic reticulum (SER) does not have ribosomes attached to it and only makes lipids. The rough endoplasmic reticulum (RER), on the other hand, does have ribosomes attached to it. The RER makes lipids as well but also helps transport the proteins made by the ribosomes attached to it.

What does the soft endoplasmic reticulum do?
Smooth Endoplasmic reticulum creates steroids and stores ions. The ion storage is important to keep the correct level of nutrients within the cell. Ion storage is like our fat cells holding on to sugars for when you need them.
What are the general functions of endoplasmic reticulum?
Two general functions are the modification and folding of proteins in the lumen of the rough ER and the manufacture of lipids in the smooth ER. Also has the important job of calcium ion storage as these ions are important second messengers in cell signaling.
What organelle releases calcium?
The endoplasmic reticulum has a store of calcium ions, Ca 2+, that it releases as second messengers in signalling transduction. Also the scarcoplasmic reticulum releases this ion in the process of sarcomere contraction.
What is the function for the smooth endoplasmic reticulum?
The smooth ER is a system of internal membrane inside the cell which move proteins and other substance through the cell (works as a highway system). The rough ER is basically smooth ER with ribosomes stuck to it. The ER is made of lipid bi-layer, just like the cell membrane.
Where is the smooth er located in a cell?
The smooth e.r. (endoplasmic reticulum) is located in the cytoplasm of eukaryotic cells. Like the rough e.r., the smooth e.r. is concerned with making proteins. Unlike the rough e.r., the smooth e.r has no ribosomes attached to it. Hope this helps. The whole article is on Wikipedia, in case this didn't help (see related link).
What is immediate source of calcium ion for muscle fiber?
The immediate source of calcium ion for muscle fiber is the sarcoplasmic reticulum, a specialized organelle within muscle cells that stores and releases calcium ions in response to nerve signals. When a muscle cell is stimulated, calcium ions are rapidly released from the sarcoplasmic reticulum into the cytoplasm, triggering muscle contraction.
Is the concentration of calcium ion greater in the sarcoplasmic reticulum or sarcoplasm of a resting muscle?
The concentration of calcium ion is greater in the sarcoplasmic reticulum compared to the sarcoplasm of a resting muscle. This is because the sarcoplasmic reticulum stores and releases calcium ions during muscle contraction.
What synthesizes proteinspackages proteins for transport and stores calcium ions?
The endoplasmic reticulum (ER) is the organelle that synthesizes proteins, packages them for transport, and stores calcium ions. The rough ER, studded with ribosomes, is primarily involved in protein synthesis, while the smooth ER plays a key role in calcium ion storage and lipid synthesis. Together, these structures facilitate the production and distribution of proteins within the cell.
What channel is ion on direct tv?
ION is on channels 216 and 217. It is available with our 120 programming packages and above.
