A biological pathway is a specific sequence of chemical reactions. It is controlled by the proteins found in the cells.
Ribosomes are responsible for assembling proteins in the cell.Ribosomes are responsible for assembling proteins in the cell.
When proteins are newly formed, they are transported to the cell surface and other parts of the cell in which require protein. These proteins are transported from the cytosol into the biosynthetic-secratory pathway located in the ER.
Ribosomes produce the proteins needed in a cell
Ribosomes make proteins on the rough ER. The proteins are packages into vesicles. The vesicles transport the newly made proteins from the rough ER to the Golgi apparautus. In the Golgi apparautus, proteins are pocessed and then packages into new versicles. Many of these varsicles move to the cells membran and release their contents outside the cell.
Ribosomes to Golgi Appartus(Body) to Endoplasmic Reticulum
Examples of secretory proteins are collagen, insulin, and digestive enzymes of the stomach and intestine.

A biological pathway is a specific sequence of chemical reactions. It is controlled by the proteins found in the cells.
A signal transduction pathway is a group of proteins that carry out transducing signals (which means it converts signals from outside the cell to a different signal inside the cell). A good example can be viewed when a hormone binds to the receptor in the plasma membrane (outside the cell), the receptor which has now been activated can now interact with intercellular proteins which produce new signals inside the cell.
Golgi bodies
The lysosomes are responsible for not only the degradation of organelles and the long-lived proteins, but they are also responsible for the repair of the plasma membrane and selective degradation of proteins, release of endocytosed material and removal of certain pathogens. When the lysosome membrane breaks down the cell is on a pathway to either apoptosis (neurogeneration and aging), autophagy (eating oneself), or necrosis (death from within).
Golgi Bodies
Ionizing radiation has the ability to harm proteins and change the sequence of DNA, causing mutations. This can have harmful effects for the cell
Protein The cell produces proteins by a process called translation. mRNA is translated at the ribosome into proteins.
Ribosomes are the cell organelles that assemble proteins. They function as factories to produce usable proteins for a cell.
