Membrane Transport Process Process Energy Source Description Examples Passive processes Simple diffusion Kinetic energy Kinetic energy Net movement of particles (ions. molecules. etc.) from an area of their higher concentration to an area of their lower concentration. that is. along their concentration gradient Movement of fats‚ oxygen‚ carbon dioxide through the lipid portion of the membrane‚ and ions through protein channels under certain conditions Osmosis Kinetic energy Simple diffusion
Premium Cell membrane Diffusion
Active transport: requires that a cell expend energy to move molecules across a membrane against the solute’s concentration gradient (the side where it is more concentrated) Feedback inhibition: Metabolic reaction is blocked by its products. A product acts as an inhibitor of one of the enzymes in the pathway to regulate metabolism. Centriole: a structure in an animal cell composed of microtubule triplets arranged in a 9+0 pattern. An animal usually has a pair of centrioles within each of its centrosomes

MECHANISM OF NORMAL LABOR By: Mrs. Ashwini Khope Lecturer‚ DES College of Nursing‚ Shivajinagar‚ Pune Mechanism of normal labor is the most important aspect to be studied in midwifery. It not only guides the actions of be performed while conducting a normal delivery but its study also ensures a safe and uneventful normal vaginal delivery. Most of us in our clinical experience must have observed how a normal delivery is conducted. But very few actually realize that in the hurry of conducting the

Jessica Wellman PHSL-P215 Paper 1 The respiratory system is protected by an innate defense system. The entire respiratory tract in lined with a mucus membrane that collects foreign particles. Once the mucus‚ or airway surface liquid (ASL) traps particles‚ mucus clearance is an essential mechanism to remove the foreign particles‚ such as dust‚ bacteria‚ viruses and other potential pathogens‚ and to keep our airways and lungs clean and free of obstruction. An important mechanism for clearing mucus involves
