What is the process of making and exporting a protein from a cell?

What is the process of making and exporting a protein from a cell?

Diffusion or facilitated diffusion. Describe the process of making and exporting protein from a cell. Ribosomes make the protein and the Endoplasmic Reticulum exports.

Which sequence of events most accurately depicts the synthesis packaging and export of a protein from a cell?

So, the correct answer is ‘Rough ER →→ Golgi apparatus →→ Cell membrane’.

Which structure is responsible for packaging proteins for export from the cell after protein synthesis is complete?

Golgi apparatus (aka Golgi body aka Golgi) It is responsible for packing proteins from the rough endoplasmic reticulum into membrane-bound vesicles (tiny compartments of lipid bilayer that store molecules) which then translocate to the cell membrane.

What are process and package proteins?

A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell. Named after its discoverer, Camillo Golgi, the Golgi body appears as a series of stacked membranes.

What are proteins packaged in?

Golgi apparatus

What is the last process of protein synthesis?

When the stop signal on mRNA is reached, the protein synthesis is terminated. The last amino acid is hydrolyzed from its t-RNA. The peptide chain leaves the ribosome. The N-formyl-methionine that was used to initiate the protein synthesis is also hydrolyzed from the completed peptide at this time.

Which of the following is required for protein synthesis to occur?

In the synthesis of protein, three types of RNA are required. The first is called ribosomal RNA (rRNA) and is used to manufacture ribosomes. Ribosomes are ultramicroscopic particles of rRNA and protein where amino acids are linked to one another during the synthesis of proteins.

Where does the second step of protein synthesis occur?

The Process Of Translation Is the Second Step Of Protein Synthesis. As already mentioned, the process of translation happens in the cytoplasm, where mRNA binds with ribosomes, which are the exact protein synthesis sites.

What are the key differences between prokaryotic and eukaryotic protein synthesis?

Explanation: Prokaryotic protein synthesis can be fairly fast because one gene can be transcribed and translated simultaneously. Eukaryotic synthesis is slower, but more precious. They can “check” the mRNA before it is translated into protein.

Is replication part of protein synthesis?

Protein synthesis makes proteins, while DNA replication makes DNA . DNA replication occurs in the nucleus and produces two identical sets of DNA. Protein syntheses produces mRNA, which is then translated by tRNA molecules carrying amino acids to produce a polypeptide or protein.

How are amino acids activated for protein synthesis?

Activation is the covalent coupling of amino acids to specific adapter molecules. The adapter molecules are called transfer RNA (tRNA). There is at least on tRNA for each of the 20 naturally occurring amino acids. The tRNA recognize the codons carried by the mRNA and position them to facilitate peptide bond formation.
