A picture of a biological membrane that includes compositional and phase heterogeneity is consistent with many observations on cells. Simons and van Meer pointed this out to explain the sorting of ...

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 ...

The table below list organelles, their function and the types of cell that they can be found in. Can you fill in the blanks to complete the table? Cell structure Description Function Cell type ...

Physical methods, such as electroporation or particle bombardment, involve rapidly changing the cell membrane to allow uptake of DNA or RNA, and chemical approaches often require attachment of the ...

Think of them as big batteries, but ones that only operate when fuel—in this case, pure hydrogen—is supplied to them. When it is, an electrochemical reaction takes place between the hydrogen ...

The team also demonstrates the key role of gamma-actin in the rigidity of cell membranes and the dynamics of junctional proteins, which may provide a mechanism of hearing loss.
