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>
        
             
        
        
        
Answer: Your brain constantly gets signals from your body which detect the amount of oxygen and carbon dioxide in your blood. Your brain will send signals to the muscles involved in breathing and adjust your breathing rate depending on how active you are.

The acetabulum is a fossa formed by the ilium, ischium and pubis which with the femoral head forms the coxal joint.
The acetabulum is made up of the three bones that make up the coxal bone (hip bone). 
The ischium, which offers the lower and side limits to the acetabulum, makes up somewhat more than two-fifths of the structure. 
Less than two-fifths of the acetabulum's structure is provided by the ilium, which also serves as the top limit of the joint. 
The pubis, which is close to the midline, forms the remainder.
The acetabulofemoral joint (art. coxae), also known as the coxal joint, is the joint between the head of the femur and the acetabulum of the pelvis. 
Its main job is to support the weight of the body in both static (such as while standing) and dynamic (such as when walking or running) postures.
