All cells have an outer plasma membrane that regulates ... Glycerol is a three-carbon molecule that functions as the backbone of these membrane lipids. Within an individual glycerophospholipid ...

these molecules have to pass across the cell membrane, which functions as a barrier — but not an impassable one. Like the exterior walls of a house, the plasma membrane is semi-permeable.

A eukaryote is any cell or organism that possesses ... Their defining feature is the presence of membrane-bound organelles, particularly the nucleus. 1 These organelles compartmentalize cellular ...

The plasma membrane has distinct regions called ... sites of Pil1 and Lsp1 alter the microdomain's shape and function, impacting yeast cell growth and stress response. The authors also demonstrate ...

The duplication and division of cells is critical to keeping all multicellular organisms alive. But the opposite process is equally important: cell death.

We attribute the eventual increase in MEA resistance with increased compression to water being squeezed out of the membrane. Figure 6A. Schematic of the sealing of the MEA in the STR PEM fuel cell.
