solute concentration through semi permeable membrane‚ which allows movement of solvent molecules‚ but not solute. The main principle of osmosis is to equalize the concentration of solute between the cells and their environment (Kent 2000). Generally‚ there are three different conditions‚ when the solution is isotonic‚ hypertonic or hypotonic to the cell. In isotonic solution‚ when water potential inside and outside the cell is equal‚ both animal and plant cell behave in the same way: there is no net

Active transport and Passive transport are biological functions that carry water‚ nutrients‚ and oxygen into cells and for the removal of waste in the cell. Active transport utilizes chemical energy to move substances from lower concentrations to higher concentrations. Whereas Passive transport moves substances from areas of high concentration to areas of low concentration‚ and it does not need to use energy. Active transport uses a chemical called ATP as its energy source in its functions. Without

was centered around the diffusion across a cellular membrane and how exactly materials move and diffuse in concentrations. Both diffusion and osmosis are forms of movement that are part of passive transport dealing with cell membranes. Diffusion is where the solutes move from an area of high concentration to a low concentration. Water goes through the cell membranes by diffusion. Osmosis is specifically the movement of water through membranes. Since osmosis and diffusion are both part of passive

Ligand binding assays are an analytical procedure‚ whose method relies on the binding of specific ligand molecules to receptors‚ antibodies or other macromolecules (Hulme et al.‚ 2010). The analysis of radioligand binding assays are based on a simple model‚ called the law of mass action‚ which assumes that binding to the receptors are reversible. The binding to the receptors occurs when the ligand and the receptor collide by diffusion and when the collision has enough energy and the correct orientation
