Facilitated diffusion

2. The element being described is Sodium its symbol is Na it has an atomic mass of 22.989769. It has an atomic number of 11. This element has 11 protons, 11 protons, and about 11 neutrons. Protons have a positive charge, electrons have a negative charge, and neutron have a neutral charge. Electron shells are the outer parts of an atom containing the electrons. Valence electrons are electrons in the outermost shell. Valence electrons tell us whether an atom shares, transfers or receives electrons…

Chemiosmosis is a type of facilitated diffusion that takes place over the plasma membrane of a cell. Chemiosmosis is based on the concentration of molecules and electrically charged atoms or ions. Not only does diffusion work to make the concentration equal on both sides of the membrane, but also to equalize charge. The molecules move from an area from a high concentration…

integral protein, cholesterols, a protein channel (for substances that can’t enter through the phospholipid bilayer), a peripheral protein, and a transport protein to pump molecules. There are six main types of cellular transport: osmosis, diffusion, facilitated diffusion, active transport, endocytosis, and exocytosis. Osmosis is the movement of water across a selectively…

used to convert glucose to glycogen, phosphorylase. The phosphorylase catalyses the reaction of glycogen back to glucose, this process is called Glycogenesis. As the levels of glucose in the cell rise, the glucose moves out of the cell by facilitated diffusion until the blood glucose levels are back at an optimum…

peripheral proteins bind substances into the cell, this is also known as the passive transport mechanism. Passive transport require no energy the most common types of passive transport are simple diffusion which passively moves the solute form higher or lower concentration in order to be balanced, facilitated diffusion which is when molecules are moved through special transport molecules within the membrane, filtration the movement of water and solute through the membrane, and osmosis which…

concentration. It does not require cellular energy. Eg carbon dioxide and oxygen. Types of passive transport: Simple diffusion: The liquid and gas particles are persistently moving about. These particles stretch from an area of higher to lower concentration. Some particles are small enough to pass through the space between the phospholipid bilayer. Eg water, oxygen and carbon dioxide Facilitated diffusion: Glucose and many other molecules are too big to travel across the membrane by themselves.…

catalysed by the transmembrane protein, adenylate cyclase, initiated by the release of GTP-bound α subunit. This increases the cytosolic levels of cAMP which then activates protein kinase A. This successively phosphorylates glycogen phosphorylase b stored in the cell, as phosphorylase kinase is initiated. Phosphorylation of glycogen phosphorylase b converts to phosphorylase a. This enzyme releases glucose-1-phosphate from glycogen polymers. After this the phosphate group is moved from the C-1…

3.1.III.D The diffusion of literary, artistic, and cultural traditions happened due to increased cross-cultural interactions. 3.1.III.E the diffusion of scientific and technological traditions occurred also due to increased cross-cultural interactions. 3.1.IV The biological effects of post-classical trade were continued diffusion of crops and pathogens along the trade routes. 3.1.IV.A New foods and crops that diffused…

design houses such as Prada, Burberry, Hermes, Gucci, Polo Ralph Lauren, Calvin Klein, and Louis Vuitton. Accessible luxury markets were the third segment in the luxury brand industry, these are luxury goods from players in the industry that created diffusion lines to compete with Coach. The accessible luxury brands offered customers luxury brand items at affordable prices. Brand rareness is another driving force industry, this heavily…

which requires a thin cell membrane for the exchange of gases used in respiration, the alveoli have extremely thin walls of about 0.5μm thick. They are also found next to the cappillaries which have thin walls aswell this means that the rate of diffusion is increased…
