and a similar electrochemical potential (about 200 millivolts [mV] across the membrane) as modern cells have. Russell has long maintained that natural proton gradients played a central role in ...

This gradient enables the proteins on the membrane to adapt to the cell shape. "The key insight is that the protein that activates Rho measures the gradient close to the membrane and marks a ...

The ability to maintain concentration gradients and sometimes move materials against them is vital to cell health and maintenance. Thanks to membrane barriers and transport proteins, the cell can ...

The cell model of ion-exchange membranes reveals violations of the Onsager reciprocity principle, particularly at high ...

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 ...

So LUCA could have been powered by natural proton gradients in vents, but only if it had a really leaky membrane, completely unlike today's cells." To escape from these seabed vents, LUCA had to ...

Mitochondria Are More Than Powerhouses—They’re the Motherboard of the Cell ...

"We found that a type of 'morphogen-gradient noise-cancelling system ... also demonstrated changes in cadherin proteins on the cell membrane, which led to an imbalance relative to cadherin ...

Researchers from the Göttingen Cluster of Excellence Multiscale Bioimaging (MBExC) have uncovered the 3D structure of the ...

This gradient enables the proteins on the membrane to adapt to the cell shape. "The key insight is that the protein that activates Rho measures the gradient close to the membrane and marks a threshold ...
