Answer: Look at the explanation sorry I cant fit the answers up here.
Explanation:
Nucleus: Initial sequence of nitrogen bases that determine type of protein comes from this organelle
Ribosome: The site of protein synthesis.
Edoplasmic reticulum: Protein assembly is completed here and proteins are readied for transport.
Golgi Apparatus: This organelle sorts and packages proteins.
Vesicle: This small/ package carries the protein to the cell membrane.
Your welcome, Btw I did this on usatestprep and got a 100.
Protein synthesis includes Transcription and Translation. Five organelles participate in the process. Transcription: Nucleus. Translation, packaging /moving: Ribosomes, Endoplasmic reticulum, Golgi complex, and Vesicles.
--------------------------------------------------------
Note: Since there are no options to match the organelle with its function, I will describe the process of protein synthesis and the function of organelles that participate in it.
Let us begin.
Protein synthesis involves two main steps: transcription and translation.
TRASNCRIPTION ⇒ mRNA syntheis
- The first step before protein synthesis begins is to synthesize messenger RNA, mRNA.
- This is the coping process of the DNA section for the desired protein, and it happens in the nucleus.
- RNA polymerase is in charge of reading the original DNI strand for mRNA synthesis.
TRANSLATION:
⇒ Cytoplasm stage
- Translation takes place when the formed mRNA moves to the cytoplasm through the nucleus membrane pores.
- Once in the cytoplasm, mRNA meets a ribosome, which is the primary structure for protein synthesis.
- Ribosomes are organelles composed by the association of proteins with rRNA and tRNA. They can be found in the rough endoplasmic reticulum or floating in the cytosol.
- While the ribosome reads mRNA strain from its 5´ extreme to 3´, tRNA adds the correct amino acids to build the polypeptide.
⇒ Endoplasmic Reticulum Stage
- Some proteins are destined for membrane or exportation. Their synthesis might start in the cytoplasm but finishes in the Rough endoplasmic reticulum.
- When the ribosome and the growing molecule reach the RER, the synthesizing protein keeps enlarging forward the reticulum lumen. When the new polypeptide synthesis is complete, it is released into the reticulum lumen.
- The endoplasmic reticulum is in charge of protein folding, maturation, and transport, especially those destined for secretion. It produces the latest protein modifications after transduction and initiates the glycosylation process.
⇒ Golgi complex stage
- Once the protein synthesis in the endoplasmic reticulum is over, these molecules are packaged into vesicles and sent to the Golgi complex.
- In the Golgi complex, proteins suffer their final association with carbohydrates to originate glycoproteins.
⇒ Destiny stage
- Glycoproteins are packaged again into new vesicles that drive them to their final destiny.
*****************************
ORGANELLE FUNCTION
Nucleus In this organelle occurs the copy process of a
DNA segment. This segment carries the genetic
information needed to synthesize a certain
protein.
Ribosome Organelle in charge of reading mRNA while
tRNA adds the correct amino
acid to the growing protein. It is the primary
structure of protein synthesis.
Endoplasmic reticulum Organelle responsible for protein folding,
maturation, and transport. It produces the
latest protein modifications of the molecule,
and initiates the glycosylation process.
Golgi Apparatus This organelle is involved of the final stages of
glycosylation. It packages the proteins into
vesicles and send them to their final destiny.
Vesicle They are actually involved in carrying
proteins to their final destiny. Some of
them get incrusted in the membrane, some
others are exported, and some others remains
in the cytoplasm.
