Chemiosmosis Definition: What is Chemiosmosis: It is the movement of ions by diffusion across a semi-permeable membrane (the membrane inside the mitochondria). Molecule ions with net electric charge as Na+, Cl-, it generates energy H+. Ions move down an electrochemical gradient in it. It is the type of diffusion, in which ions move across a membrane from high concentration are… Read More »

Serous Membrane Serous Membrane Definition: The serous membrane is defined as a thin membrane that lines the internal body cavities and the organs including the heart, lungs and abdominal cavity. The thin membrane of the serous membranes is composed of mesothelium tissue that originates from mesoderm. The serous membranes permits for functionless movement lies in a number of… Read More »
