Endomembrane System—processes proteins determined by DNA, and assembles the
products; it then sorts and transports them to their final destinations
Nucleus with DNA—DNA produces RNA that delivers the plan to the ribosomes
Ribos are typically located at RER, which is continuous with NUCLEAR ENVELOPE
and proteins are made; the RER modifies the proteins as they move through, some are
packaged into vesicles that are released.
Other proteins continue through to the SER where they become enzymes; still others are
released into vesicles.
Vesicles released from ER move on to the GOLGI, the vesicles fuse to the GOLGI and
release their content into the GOLGI where they are modified yet again and “tagged for
delivery.”
Final products are released in vesicles, some stay with the cell, like LYSOSOMES, and
still others leave the cell (like adrenalin).
Because of vesicles, proteins and lipids can be recycled between these organelles and the
CM---since they all have the phospholipid bilayer in common.
