2.1.2 Membrane proteins Cell membranes exhibit outstanding permselectivity that promote certain substances permeating cell membranes. There are three means through which water and other small molecules cross into or out of cells, known as simple diffusion, facilitated diffusion and active transport. Small...

In recent years, we have begun to understand how membrane remodelling is coordinated during division; however, there is still much to learn. In this Review, we discuss recent insights into how these important cellular events are performed and regulated. This is a preview of subscription content,...
Krishnagopal Dharani, in The Biology of Thought, 2015 Cell Membrane The essential feature of every cell is the presence of a membrane (=plasma membrane), which defines its boundaries. The cell membrane also limits the boundaries of cytoplasmic organelles such as mitochondria, nucleus, endoplasmic ...
“tissue” in biology [11]. This line of thought lasted until the early XIXthcentury; its last proponent was Mirbel, who assumed that the whole plant organism was made of a uniquemembranousstructure (note here that the terms “membrane” and “cell wall” were indistinctly used at that ...
Figure 4. Simple Diffusion across the Cell (Plasma) Membrane.The structure of the lipid bilayer allows only small, non-polar substances such as oxygen and carbon dioxide to pass through the cell membrane, down their concentration gradient, by simple diffusion. ...
