Proteins leave the cell through a process called exocytosis, where they are packaged into vesicles and transported to the cell membrane. The vesicle then fuses with the cell membrane, releasing the proteins outside of 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.
false
Ribosomal proteins are synthesized in the cytoplasm of the cell.
Proteins are manufactured in the cell at the ribosomes, which are the organelles responsible for protein synthesis.
Mitochondrial proteins are made in the cytoplasm of the cell, not within the mitochondria themselves.
Proteins enter and leave the cell through endocytosis and exocytosis, respectively.
Proteins made on "bound" (attached) ribosomes leave through the cell membrane, and other proteins will enter the cell.
The only things that enter and leave cells are molecules and proteins. organelles do not 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 that are attached to the ribosomes, I suppose
Proteins made on "bound" (attached) ribosomes leave through the cell membrane, and other proteins will enter the cell.
Transport proteins allow nutrients to enter and leave cells. Transport proteins are peppered throughout the cell membrane. Most molecules need the transport proteins to enter or leave the cell, but it's possible for some molecules, like water, to diffuse through the membrane by osmosis.
Copies of DNA do not leave the cell, they split, rebuild into two daughter copies, and then separate into opposite sides of the cell, which then divides. The DNA never passes the plasma membrane of the cell. Answer In vessicles.
The phospholipid bilayer of the plasma membrane, specifically the integral membrane proteins like transport proteins and ion channels, regulate what enters and leaves the cell by controlling the movement of molecules across the membrane.
They are packaged by the Golgi bodies for use either within the cell or for secretion from the cell.
Ribosomes are the cell organelles that assemble proteins. They function as factories to produce usable proteins for a cell.
There are two kinds of proteins in a cell membrane: peripheral PROTEINS OR trans membrane proteins. Cell membranes are able to perform various functions only because of different membrane protein functions. Most of the membrane proteins have alpha helix structure.
