Proteins are destined for various functions within and outside the cell, including acting as enzymes to catalyze biochemical reactions, providing structural support, and facilitating communication between cells. Some proteins are targeted to specific organelles, such as mitochondria or the endoplasmic reticulum, while others are secreted outside the cell to perform roles in signaling or immune response. The specific destination of a protein is determined by its amino acid sequence, which includes signal peptides that guide it to the correct location.
What else can I help you with?
What Produces proteins destined for secretion from the cell and contains ribosomes?
The rough endoplasmic reticulum (rough ER) is responsible for producing proteins destined for secretion from the cell. It is studded with ribosomes on its cytoplasmic surface, which synthesize proteins that are then folded and modified within the ER. These proteins are eventually packaged into vesicles for transport to the Golgi apparatus, where they undergo further processing before secretion.
What is the function of the rough endoplasmic reticulum in the mammalian cell?
Rough endoplasmic reticulum is studded with ribosomes, which make proteins. It makes proteins that are destined to leave the cell to go elsewhere, for example, proteins in a mothers breast mild.
What Membrane-enclosed organelles modifies sorts and packages proteins destined for other regions of the cell (?
The organelle responsible for modifying, sorting, and packaging proteins destined for other regions of the cell is the Golgi apparatus. It receives proteins from the endoplasmic reticulum, processes them through a series of cisternae, and then directs them to their appropriate locations, whether inside the cell or for secretion outside the cell. The Golgi apparatus plays a crucial role in post-translational modification and ensuring proteins reach their functional sites.
What type of proteins are made in the ER?
Proteins synthesized in the endoplasmic reticulum (ER) include secretory proteins, membrane proteins, and proteins destined for lysosomes. The rough ER, which is studded with ribosomes, is primarily responsible for producing these proteins, which undergo folding and modifications like glycosylation. Once synthesized, they are packaged into vesicles for transport to their final destinations, such as the Golgi apparatus.
Which structure makes final modifications on and packages proteins that will leave the cell?
The structure that makes final modifications on and packages proteins destined to leave the cell is the Golgi apparatus. It receives proteins from the endoplasmic reticulum, processes them by adding carbohydrate or lipid groups, and then sorts and packages them into vesicles for transport. These vesicles then carry the modified proteins to their final destinations, either within the cell or outside of it.
Why are most proteins destined for secretion from the cell glycoproteins?
Proteins destined for secretion are modified in the endoplasmic reticulum and Golgi apparatus to become glycoproteins. These carbohydrate modifications help with protein folding, stability, and recognition by other cells. Glycoproteins also play a role in cell-cell communication and immune response.

What is the function of an attached ribosome?
An attached ribosome synthesizes proteins destined for the secretory pathway directly into the rough endoplasmic reticulum.

Where travel proteins?
Cellular (transported) proteins travels around the cell and sometimes destined to the particular organelle where it does its function. Secreted proteins such as albumin or hemogolbin are carrier proteins. Hemoglobin carries oxygen and carbon dioxide all over the body through blood tissue.
What are the types of proteins synthesize in the free ribosome?
Free ribosomes synthesize proteins that are soluble in the cytoplasm, such as enzymes, structural proteins, and proteins involved in intracellular signaling pathways. These proteins do not have a specific subcellular localization and function within the cytoplasm of the cell.
What type of proteins are made in the ER?
Proteins synthesized in the endoplasmic reticulum (ER) include secretory proteins, membrane proteins, and proteins destined for lysosomes. The rough ER, which is studded with ribosomes, is primarily responsible for producing these proteins, which undergo folding and modifications like glycosylation. Once synthesized, they are packaged into vesicles for transport to their final destinations, such as the Golgi apparatus.
What part of the cell takes proteins and changes them so that they are ready to leave the cell?
The Golgi apparatus is the part of the cell that modifies, sorts, and packages proteins into vesicles for transport outside of the cell. It acts as a processing and distribution center for proteins destined for secretion.
Proteins destined for export from the cell are synthesized with a signal sequence and begin their synthesis?
Proteins destined for export from the cell are synthesized with a signal sequence at the N-terminal, which guides them to the endoplasmic reticulum (ER). The signal sequence interacts with the signal recognition particle (SRP) to target the ribosome-nascent chain complex to the ER membrane for translocation. This process ensures proper trafficking and secretion of the protein.
Which function is associated with the rough endoplasmic reticulum?
The rough endoplasmic reticulum is associated with protein synthesis due to the presence of ribosomes on its surface. It plays a key role in the translation and processing of proteins destined for secretion or insertion into cell membranes.
Which structure makes final modifications on and packages proteins that will leave the cell?
The structure that makes final modifications on and packages proteins destined to leave the cell is the Golgi apparatus. It receives proteins from the endoplasmic reticulum, processes them by adding carbohydrate or lipid groups, and then sorts and packages them into vesicles for transport. These vesicles then carry the modified proteins to their final destinations, either within the cell or outside of it.
