You can make a song. That's how I memorized it.
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>
The 16 refers to the atomic mass, the total number of protons and neutrons in the nucleus.
We know Oxygen has atomic number of 8, this can be seen by looking at a periodic table.
This means Oxygen must have 8 protons in the nucleus.
As:
<em>Neutrons + Protons = 16,
</em>
And the number of protons = 8,
<em>Neutrons </em>+ 8 = 16
<em>
</em><em>Neutrons = 8
</em>
There are 8 Neutrons in the nucleus.
