Cellular Biology- Ribosomes

Question 1

Ribosomes

Answer 1

RNA complexes, nucleoproteins, that are synthesized in the nucleosis and secreted into the cytoplasm through pores in the nuclear envelope called nuclear pore complexes, and NPCs

Question 2

Ribosomes can float…

Answer 2

Freely in the cytoplasm or attach themselves to the outer membrane of the endoplasmic reticulum

Question 3

Chief function of ribosomes

Answer 3

To provide sites for cellular protein synthesis

Question 4

Newly Formed Ribosomes…

Answer 4

Synthesize “recognition sequence” for signal like an address on a letter

Question 5

SRP’s

Answer 5

Signal recognition particles

In the cytosol bind to ribosomes after recognizing the SRP

Question 6

Ribophorins

Answer 6

Receiver proteins found on the rough sections of the endoplasmic reticulum, act as the address side or binding site

Question 7

Developing protein threads it’s way through…

Answer 7

The endoplasmic reticulum membrane into the lumen

Then the SRP is removed and the new protein chain is folded into its Final confirmation
