Which is part of the cell makes proteins?

Which is part of the cell makes proteins?

Proteins are made up of amino acids, and all of them need to be joined correctly so the protein can do its job properly. When a cell makes a protein, the nucleus forms messenger RNA, or mRNA.

Which is the packaging center of the cell?

The Golgi Apparatus is the “packaging center” for the cell. This structure receives protein material from the endoplasmic reticulum, processes this protein material into a macromolecule the cell can use, then packages it for transport through out the cell. (Kind of like how a postal service or UPS packs and delievers packages)

Where does a protein go after it leaves the ribosome?

For proteins destined for export out of the cell, after a very short sequence of the amino acid chain has grown from the ribosome, the ribosome, bound up with its mRNA and amino acid chain, will migrate to the rough endoplasmic reticulum (RER) and dock on its outside face, thus joining many other ribosomes that have done the same thing.

Where does the synthesis of proteins take place?

Protein synthesis is a complicated process which occurs in many different parts of the cell. Transcription occurs in the nucleus and translation occurs at a ribosome. The protein assumes its 3D shape in the rER and is modified in the Golgi apparatus. The synthesis of proteins from messenger RNA (mRNA) is known as translation.

What packages and distributes proteins in the cell?

A structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell. Endoplasmic reticulum A system of membranes that is found in a cell’s cytoplasm and that assists in the processing and transport of proteins.

What packs and carries proteins in a cell?

Proteins manufactured in the rough endoplasmic reticulum enter the Golgi apparatus and are packed into vesicles capable of fusing with the plasma membrane in order to facilitate transport of the protein out of the cell.

What carries proteins from one part of the cell to the other?

Carrier proteins are proteins that carry substances from one side of a biological membrane to the other. Many carrier proteins are found in a cell ‘s membrane, though they may also be found in the membranes of internal organelles such as the mitochondria, chloroplasts, nucleolus, and others.

What packages protein for transport out of the cell?

These break down proteins, carbohydrates and lipids for use by the cell. Golgi complex (body, apparatus) This organelle packages proteins for transport out of a cell or for storage within the cell.
