It is the serous membrane
Ost proteins that function in the cytosol (such as actin) or in the nucleus (such as DNA polymerase) are synthesized by free ribosomes. Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes.
<span>As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen.</span>
IN THE LUMEN INSIDE OF THE ENDOPLASMIC RECTICULUM.
<u>Explanation:</u>
The endoplasmic recticulum is the continuous membrane system that forms that forms the more number of flattened within the cytoplasm of eukaryotic cells and performs the multiple process in the cell.
The immportant functions of endoplasmic recticulum is folding, synthesis, modification, ans transport of the protein. The lumen is the protein which is present in the endoplasmic recticulum.
The lumen of the endoplasmic recticulum is the area closed by the endoplasmic recticulum membrane, it is an extensive network of the membrane tubues, visicles, and flattened the cisternae found in the eukaryotic cells.
Answer:
Telescope also known as "spyglass"
Explanation:
In 1609, using this early version of the telescope, Galileo became the first person to record observations of the sky made with the help of a telescope. He soon made his first astronomical discovery.
