A. The ribosomes lining the cell membrane will make it so it can be sent out of the cell more quickly.
B.The ribosomes surrounding the Golgi apparatus will make it so it can be more easily captured and wrapped in membrane.
C.The ribosomes on the endoplasmic reticulum will make it so it can be wrapped in membrane and sent to the Golgi apparatus.
D.The ribosomes floating in the cytoplasm will make it so it can be bent into the correct shape.

The right answer is C. Ribosomes are more or less located in two general areas - freely in the cytosol or attached to the rough endoplasmic reticulum. Now, you know that these proteins will be secreted. Keep in mind then, that ribosomes associated with the ER create their proteins in the lumen or interior of the ER. The ER then packages these proteins into vesicles and secretes them to the Golgi, which secretes them to the membrane. So, ER-associated ribosomes are bound by vesicles, and free ribosomes in the cytosol create proteins are not. I hope that this is the answer that you were looking for and it has helped you.

Answer:
option 1
Explanation:
In assemblying the nucleosome, this reaction occurs in two main steps. the H3 and H4 are recruited first to the DNA in pairs forming the H3/H4 tetramer; meaning two of H3 and two of H4. This gives rise to the nucleosome precursor. Then after this, the dimers of both H2A/H2B are recruited to this precursor, to give rise to the octamer structure around which the DNA is wrapped.
Answer:
What can be noticed about the ligands and their receptor is that the configuration of both coincide, as a key would with its lock, which demonstrates the specificity of a receptor by its ligand.
Explanation:
A <u>ligand</u> corresponds to a molecule considered a signal or a messenger, while the <u>receptor</u> is a protein on the cell surface, with the capacity to accept a ligand.
Ligands and receptors constitute pairs that complement each other, so that <u>each receptor can bind to a specific ligand</u>, similar to what happens with a key and a lock.
Once the ligand-receptor complex is formed, changes occur inside the cell, which define a certain effect.
