PATHOLOGY

Detailed explanation-1: -A maze of passageways called the endoplasmic reticulum carries proteins and other materials from one part of the cell to another. Small, grainlike bodies called ribosomes produce proteins. Collections of sacs and tubes called Golgi bodies distribute proteins and other materials throughout the cell.

Detailed explanation-2: -Vesicular transport from the ER to the Golgi. Proteins and lipids are carried from the ER to the Golgi in transport vesicles that bud from the membrane of the ER and then fuse to form the vesicles and tubules of the ER-Golgi intermediate compartment (ERGIC).

Detailed explanation-3: -The endoplasmic reticulum (ER) is a dynamic organelle responsible for many cellular functions, including the synthesis of proteins and lipids, and regulation of intracellular calcium levels.

Detailed explanation-4: -The Golgi apparatus transports and modifies proteins in eukaryotic cells.
