Which set of organelles traces the path of a protein from creation to use in the cell?
Endoplasmic reticulum is a network of membranes inside a cell through which proteins and other molecules move. Proteins are assembled at organelles called ribosomes.
What structure makes proteins in a cell?
Ribosomes
Ribosomes produce proteins and are made of two components—RNA and protein. Ribosomes are produced in the nucleolus, a structure located inside the nucleus. Some ribosomes float freely in the cytoplasm. They produce proteins that will be used by other cells.
What is the correct order of molecules involved in protein synthesis?
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell’s ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein …
What is the path of protein?
Proteins enter the secretory/biosynthetic pathway in a specialized organelle called the endoplasmic reticulum (ER), where they fold and acquire transport competence (Figure 1). Upon exiting the ER, proteins enter the stacks of the Golgi apparatus, which contain numerous enzymes that modify glycoproteins.
What of the following shows the correct sequence for the production of a protein?
The correct sequence of events in protein synthesis is transcription, then translation.
Which of the following correctly lists the pathway of a protein from synthesis to transport out of the cell?
Rough ER → Golgi apparatus → Cell membrane.
How is protein released from a cell?
Protein from your diet is broken down into individual amino acids which are reassembled by your ribosomes into proteins that your cells need. Ribosomes do not produce energy. If the protein is going to be used within the cytoplasm of the cell, the ribosome creating the protein will be free-floating in the cytoplasm.
