In biology textbooks, the endoplasmic reticulum is often portrayed as a distinct, compact organelle near the nucleus, and is commonly known to be responsible for protein trafficking and secretion. In ...

Cells have extensive sets of intracellular membranes, which together compose the endomembrane system. The endomembrane system was first discovered in the late 1800s when scientist Camillo Golgi ...

There are two types of ER in a cell – rough ER and smooth ER – that together form a single continuous membrane network within the cell’s cytoplasm. The rough ER membrane is studded with ribosomes, ...

The peripheral endoplasmic reticulum (ER) forms a continuous ... and ions throughout the cell. "The ability to maintain large, complex structures in the face of constant turnover is a defining ...

New research details the subcellular structures in neurons that enable signals to be transmitted from where they are received at specific sites on dendrites to the decision-making cell body located ...

In this way, membranes are continually recycled and reused for different purposes throughout the cell. Membrane transport also occurs between the endoplasmic reticulum and the Golgi.
