Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of ribosome creates the most proteins that are used by the cell?
A
bound
B
free-floating
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Free ribosomes, unattached to any membrane, synthesize all other proteins encoded by the nuclear genome. Membrane-bound and free ribosomes are structurally and functionally identical. They differ only in the proteins they are making at any given time.

Detailed explanation-2: -They are known as free ribosomes. These ribosomes group together and form structures called polysomes. They are freely floating in the cytoplasm and move all around the cell.

Detailed explanation-3: -The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
