Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Which part of the cell makes proteins and can be found on the rough ER?

A	Centrioles
B	Chloroplasts
C	Golgi
D	Ribosomes

Explanation:

Detailed explanation-1: -The ribosome that is synthesizing the protein is directly attached to the ER membrane. These membrane-bound ribosomes coat the surface of the ER, creating regions termed rough endoplasmic reticulum, or rough ER (Figure 12-36A).

Detailed explanation-2: -The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins. Sometimes, when those proteins are made improperly, the proteins stay within the endoplasmic reticulum.

Detailed explanation-3: -Many proteins that are synthesized in the RER are packaged into vesicles and transported to the Golgi apparatus.

Detailed explanation-4: -The endoplasmic reticulum (ER) is a structure found within the cytoplasm of eukaryotic cells. Its composition has two components: the smooth endoplasmic reticulum (SER) and the rough endoplasmic reticulum (RER).

Detailed explanation-5: -The rough endoplasmic reticulum contains ribosomes and makes protein, whereas the smooth endoplasmic reticulum does not contain ribosomes and functions to make lipids and detoxify the cell.
