Molecular pumps-when a cell uses energy to pump molecules across the membrane through a protein channel. Facilitated diffusion- a transport of protein acts as a protein channel to help the diffusion of molecules that normally couldn't pass through the cell membrane C: Active transport-some molecules have to be pushed "uphill" against a concentration gradient i. Daily life example is also included in this video lesson. Isotonic- identical water concentrations to what is found in cell's cytoplasm. Hypertonic, hypotonic and isotonic solutions are also elaborated to make the concept of. But let’s break down IV solution memorization even more. This means that no osmosis or shifting is happening with the cell. Isotonic fluids can be considered isoperfect cells, like I’m so perfect. A hypotonic Isotonic solutions An isotonic solution has the same osmolarity ( or tonicity ) as serum and other body fluids. The opposite effect to a hypotonic solution occurs within the cell. In a hypertonic solution, the concentration of solutes in a solution is higher outside the cell. The aim is to produce an isotonic solution on both sides. Hypotonic- water concentration is above what is found in cell's cytoplasm. Hypotonic fluids can be considered hippotonic cells because all the fluid goes into the cell causing it to swell. In an extracellular hypertonic solution, water will exit the cell to lower high concentrations outside the membrane. Hypertonic- water concentration is below what is found in a cell's cytoplasm. Osmosis-the diffusion of water across the cell membrane 1. Diffusion- spreading of molecules across a membrane until they are equally concentrated on both sides of the membrane. A: Homeostasis-the need of an organism to maintain and regulate constant/stable internal conditions B: Passive transport- i.
