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.
Transport of molecules within a cell and out of the cell requires a complex endomembrane system. Endocytosis occurs when the cell membrane engulfs particles (dark blue) outside the cell ...
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 ...
It is essential for bioenergetics (ATP, GTP), metabolic regulation through glycolysis and oxidative phosphorylation, intercellular signaling pathways, cell proliferation (as part of DNA and RNA ...
This method could open new frontiers in ... For the study, the researchers aimed to functionalize the cell membrane to enable protein transport across the membrane and assemble them into tissue ...
The net movement of water from a region of high water concentration to a region of low water concentration through a selectively permeable membrane. This means osmosis is a special case of ...
When transport processes in cells do not function properly, this often results in diseases such as metabolic disorders, high blood pressure, kidney and lung damage or inflammation. In the ...
Lipid bilayer forms a water-impermeable barrier that defines the boundary of a cell ... transport proteins that facilitate transmembrane flux of ions and small molecules, and membrane-embedded enzymes ...
Understanding bacterial growth mechanisms can potentially help uncover novel drug targets that are crucial for maintaining cellular viability, particularly for bacterial pathogens. In this important ...
