This lesson is on transport across the cell membrane. In this lesson, we'll review what a cell membrane is and what it's made of, and learn in detail about the three types of transport across the membrane. What Is the Cell Membrane? At a high security building, humans use doors, ...
membrane potential unequal distribution of charges across a plasma membrane, negative inside the cell positive outside, both sides attract like a battery the membranes permeability, sodium potassium pump moves more positivity out then it takes in and negatively charged ions that cannot get out what ...
the cell membrane (also known as the plasma membrane) separates the inner contents of a cell from its exterior environment. This cell membrane provides a protective barrier around the cell

In biological systems, ion transport across the cell membrane is mostly directional, an embodiment of ionic rectification1. Unidirectional ion transport is related to an asymmetric biological nanopore structure, in which the ionic flow in one direction is almost totally suppressed2. This is essential ...
Transport Across the Cell Membrane One of the most prominent features of a living cell is transport of materials across membranes. We have already discussed transport of materials by diffusion or through various channels, transporters and pumps (see p. 4, Table 1.1). Another important means of ...
