Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike ...

A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment.

The outermost membrane that encloses the cell as a whole is called the “plasma membrane. ” All cellular membranes have a general structure comprising a bilayer of molecules having affinity to both fat ...

In this interview Prof. Dr. Kristina Kusche-Vihrog speaks about the nanomechanics of living cells and their implications for ...

Advanced techniques are allowing scientists to witness the process where plant cells generate cellulose fibers.

First, they isolated iridocytes from squid (Doryteuthis opalescens) and examined the cells’ surface using a high-resolution scanning electron microscope. To their surprise, they saw that the grooves ...

Researchers knew, for instance, that HIV wraps its core viral components in a lipid envelope formed from the host plasma membrane. However, they were uncertain about how HIV controls the remodeling of ...

Throwing new light into this domain, the NCBS scientists have proposed that Esyt possesses a C2 domain capable of binding and ...
