Aerobic Respiration Breaking down glucose to release energy Products are Carbon dioxide and water Diffusion is … the movement of molecules from a region of high concentration to a low concentration until the concentration is equal. Role of a human circulatory system: Diffuse In – oxygen (O2)‚ dissolved food (glucose) and water (H2O) Diffuse Out – carbon dioxide (CO2)‚waste and water(H2O) Respiration – releasing energy in cells Breathing – getting air into and out of your body

non-penetrating solutes.[2] Penetrating solutes can diffuse through the cell membrane‚ causing momentary changes in cell volume as the solutes "pull" water molecules with them. Non-penetrating solutes cannot cross the cell membrane‚ and therefore osmosis of water must occur for the solutions to reach equilibrium. A solution can be both hyperosmotic and isotonic.[2] For example‚ the intracellular fluid and extracellular can be hyperosmotic‚ but isotonic – if the total concentration of solutes in

(NaCl) concentrations of 0.1M‚ 0.2M‚ 0.3M‚ 0.4M‚ 0.5M‚ 0.6M. Hypothesis: When the water concentration of a solution outside the cell is lower than the concentration inside the cell‚ water will move from the inside to the outside of the cell due to osmosis. As we increase the concentration of the NaCl solutions we have used (0.1M to 0.6M)‚ more moles of NaCl are dissolved in the solution. Thus‚ the solutions increases in solute concentration but decreases in water concentration. We can therefore assume;

passive transport mechanisms include diffusion‚ osmosis‚ and facilitated diffusion. Diffusion is the movement of materials from an area of most concentrated to an area of least concentrated‚ which is equal to moving down a concentration gradient. When the molecules have reached equal concentrations in both locations‚ diffusion ends and it has reached equilibrium. Molecules continue to move‚ but move in both directions equally; there is no net change! Osmosis is the movement of water. It moves water

type is active processes which use energy known as ATP to power the transport. There are two main types of passive processes called diffusion and filtration. This can be split into different types such as simple diffisuion‚ facilitated diffusion‚ osmosis and filtration. The objective of these experiments is to provide information on the passage of solutes and water through semi permeable membranes and relate them back to the study of actual living membranes in the human body. The purpose is to

behind diffusion and osmosis. Permeability‚ concentration gradients‚ plasmolysis‚ water potential‚ and equilibrium were also concepts that were delved into in this lab. Understanding how diffusion and osmosis works is essential to understanding biology. Each time a cell has something move into or out of it‚ some sort of principle studied in this lab is occurring. Diffusion‚ osmosis‚ and passive and active transport are all fundamental concepts of Biology. This lab simulated osmosis in the cell. In this

Introduction: 1. The purpose of doing this lab was to recognize the effects that salt‚ in different strengths‚ has on cells. 2. Osmosis is the movement of water molecules

Movement in and out of cells Diffusion: (mixing molecules) Molecules and ions in a liquid or a gas move continuously. The movement is quite random‚ and the particles change direction as they bump into one another. The particles collide more often when they are close together (when they are concentrated) and so they tend to diffuse‚ or spread out‚ until they are spaced evenly throughout the gas or liquid. The random movement of particles is due to their own kinetic energy. When the diffusion

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. Because of the selective permeability of the membrane only water and other very small particles (iodine) can be diffused through simple diffusion. The solution out of the dialysis tubing had a higher distelled iodine concentration of solutes (iodine + H2O) than did the starch solution. So iodine move into the cell and react with starch molecules to formed starchiodine‚ the blue compound
