Describe the difference between diffusion and osmosis?
although both are the movement of particles from an area of high concentration to low, diffusion is the movement of many kinds of substances however osmosis refers to the diffusion of water particles only from an area of high water concentration to an area of low water concentration.
How do diffusion and osmosis differ from one another?
Diffusion and osmosis differ because diffusion is the process by which molecules spread out, or move from areas with high concentration to low concentration, and osmosis is the diffusion of water. Osmosis is a type of diffusion relating to water. It is usually used to describe the diffusion of water across a membrane (such as the cell membrane). Osmosis is also defined as the flow of solvent from a region of higher pressure toward a region of low pressure.
What is the process in which molecules move from an area of higher concentration to lower concentration?
Diffusion is the movement of particles from an area of high concentration to an area of low concentration--not to be confused with osmosis, which is the movement of water through a semi-permeable membrane.
How do molecules diffuse?
Movement of solutes across a lipid bilayer plasma membrane can occur in many ways:1. Osmosis: diffusion of water across membranes to balance solute concentrations.- No energy req- Water passes through membrane via aquaporins, pores in the membrane permeable only to water.2. Simple diffusion: diffusion of only small, hydrophobic (nonpolar) molecules across a membrane down their concentration gradient.- No energy req- Only moves small nonpolar molecules down their concentration gradient3. Facilitated diffusion (passive transport): uses transmembrane protein transporters (channels and carriers) to move polar molecules (ions) across a membrane- No energy required- Channel proteins: Allow for rapid diffusion of specific ions down their concentration gradient- Can be activated by:- Voltage- Ligand- Mechanical force- Carrier proteins: Allow for selective diffusion of specific ions down their concentration gradient.- Uniport carriers: only transport one specific ion down its concentration gradient- Symport carriers: move two different types of ions in the same direction.- Antiport carriers: moves two different ions in opposite directions-Can use the energy created moving one molecule down its concentration gradient to move an ion against its concentration gradient- Carrier proteins exhibit saturation, competition, and specificity.4. Active transport: transport of solutes across a membrane against their concentration gradient.- ATP req- Uses carrier proteins- Leads to creation of potential energy stored in electrochemical gradients
What factors influence the passage of substances through living membranes?
One factor that influence the passage of substances through living membranes are size which small molecules pass faster than large. Others are the charge non polar are faster and concentration gradient molecules that move to regions of lower concentration.
What make osmosis and diffusion the same?
Molecules travel across the cell membrane from a higher concentration to a lower concentration during both osmosis and diffusion. Diffusion is when molecules move across the cells' membrane from a higher concentration to a lower concentration. Osmosis is the diffusion of water.
Can diffusion occur without membrane?
Diffusion is the movement of molecules kineticly from an area of high concentration to an area of low concentration until they are evenly distributed. Osmosis is the movement of molecules thru a membrane.
Diffusion is defined as a movement of molecules?
Is Diffusion the movement of molecules from a greater to a lesser concentration.
How would you define diffusion?
Cellular diffusion is when molecules in the cell go from high concentration to low concentration to balance out the concentration. Small molecules can diffuse through the cell membrane, but larger molecules need the help of proteins. This is call facilitated diffusion.
The roles of Osmosis and diffusion?
Diffusion - the process by which molecules spread from areas of high concentration, to areas of low concentration. Osmosis - the diffusion of water (across a membrane)
How would you define cellular diffusion?
Cellular diffusion is when molecules in the cell go from high concentration to low concentration to balance out the concentration. Small molecules can diffuse through the cell membrane, but larger molecules need the help of proteins. This is call facilitated diffusion.
How do cells use the process of osmosis and diffusion to take in nutrients and to get rid of wastes?
== == Diffusion is: the movement of particles from regions of higher concentration to regions of lower concentration. Osmosis is: the diffusion of water through a semipermeable membrane.
What term describes the diffusion of the water through a semipermeable membrane down a concentration gradient?
Osmosis is the diffusion of water molecules down a concentration gradient through a semi-permeable membrane
What is diffusion of oxygen all about?
Diffusion is the main method by which molecules move across the cell membrane. during diffusion, molecules move from an area of higher concentration, to an area of lower concentration. What is Osmosis? Osmosis is the transport of water from an area of high concentration, to an area of low concentration water moves inside and inside of the cell membrane by osmosis. osmosis is the diffusion of water!
What happens to a higher concentration of dissolved molecules on one side of a cell membrane during the process of diffusion?
the side of the cell membrane with the higher molecule concentration moves molecules to areas of lower concentration during diffusion until an equilibrium is reached between both sides of the membrane.
Can you have diffusion without osmosis?
Osmosis is the movement of water molecules across a semipermeable membrane from a region of higher concentration to a region of lower concentration. Diffusion is the movement of any molecules from a region of higher concentration to a region of lower concentration. so yes it is possible to have diffusion without osmosis.
How do diffusion osmosis facilitated diffusion and active transport diffusion differ?
Diffusion is the movement of molecules from an area of greater concentration to an area of lesser concentration. e.g. Exchange of gases in the lungs or body tissues. Osmosis is the diffusion of water through a semi-permeable membrane from an area of low solute to an area of high solute concentration. Faciliated diffusion is the passive transport of molecules down a concentration gradient. It is simply diffusion that involves a protein to make diffusion happen more easily across a cell membrane. Active transport is the moving of substances across the cell membrane using the cell's energy. Molecules are moved against a concentration gradient, i.e they move from an area of lesser concentration to an area of greater concentration. Tlhis is done by a carrier molecules which gets its energy from ATP.
