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 ...

The fatty membrane surrounding every living cell is a vibrant environment where countless biological processes take place.

The myelin lamella is formed by fusion of the apposed inner leaflets of the plasma membrane in glial cells, with no intervening cytoplasm (Figure 1B). Depending on the location, different glial ...

To switch on the cell death signal, just 15% of all CD95 receptors on the cell membrane need to bind in twos or threes around ...

Animal and plant cells differ and they have similarities. Nucleus, cell membrane, cytoplasm and mitochondria are four cell components that are found in both animal and plant cells. All life on ...

the cell membrane, every day and have to repair them again. Researchers at the University of Münster have now identified the processes that enable the precise closure of such membrane injuries.

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

2 Endosymbiotic events are believed to have led to the development of membrane-bound organelles such as mitochondria. Thanks to mitochondria, eukaryotic ancestors had enough energy to develop into the ...

A new approach to elucidate the operation and control of Polymer Electrolyte Membrane (PEM) fuel cells is being developed. A global reactor engineering approach is applied to PEM fuel cells to ...
