Diagram of a plant cell and its constituent organelles. --> ... 1 Outer membrane. 1.1 Porin. ... An example of the template with all diagrams activated.
Thermodynamically the flow of substances from one compartment to another can occur in the direction of a concentration or electrochemical gradient or against it. If the exchange of substances occurs in the direction of the gradient, that is, in the direction of decreasing potential, there is no requirement for an input of energy from outside the system; if, however, the transport is against ...
The cell membrane, also called the plasma membrane or plasmalemma, is a semipermeable lipid bilayer common to all living cells.

To change this template's initial visibility, the |state= parameter may be used: {{Membrane transport | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Membrane transport | state = expanded}} will show the template expanded, i.e. fully visible.
Intracellular transport is the movement of vesicles and substances within a cell. Intracellular transport is required for maintaining homeostasis within the cell by responding to physiological signals. [1] Proteins synthesized in the cytosol are distributed to their respective organelles, according to their specific amino acid’s sorting ...
In cellular biology, active transport is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. Active transport requires cellular energy to achieve this movement.
The solute carrier (SLC) group of membrane transport proteins include over 400 members organized into 66 families. [ 1 ] [ 2 ] Most members of the SLC group are located in the cell membrane . The SLC gene nomenclature system was originally proposed by the HUGO Gene Nomenclature Committee ( HGNC ) and is the basis for the official HGNC names of ...
Comparison of transport proteins. A symporter is an integral membrane protein that is involved in the transport of two (or more) different molecules across the cell membrane in the same direction. The symporter works in the plasma membrane and molecules are transported across the cell membrane at the same time, and is, therefore, a type of ...
