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 ...

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

Inside cells, there exists an extensive system of canals known as the endoplasmic reticulum (ER), which consists of membrane-encased tubes that are partially broken down as needed—for instance ...

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 ...

The endoplasmic reticulum (ER) is a crucial organelle present in all eukaryotic cells, including human cells. The ER plays a ...

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.

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, ...
