During active transport substances move from regions of what?
in active transport, where do molecules always go
Does active transport move from higher to lower concentration?
Active Transport- When molecules move from an area of lower concentration to an area of higher concentrationPassive Transport- When molecules move from an area of higher concentration ot an area of higher concentration (also called diffusion)
A solution containing a higher concentration of dissolved substances than the cell is termed?
There are two types of solutions categorized by solute concentration. If the solution has a higher saline concentration than the erythrocytes (red blood cells) it is said to be hypertonic. If the opposite is true the solution is then hypotonic.
Which ions electrical charges oppose the direction of movement that is caused by their concentration gradient?
Any ion that is positive but has a higher concentration inside the cell or is negative and has a higher concentration outside the cell. Any ion that is positive but has a higher concentration inside the cell or is negative and has a higher concentration outside the cell.
What is a solution that has a lower solute concentration and a higher water concentration then another solution?
Hypotonic is the term describes a solution that has a lower solute concentration and higher water concentration than another solution Hypertonic describes a solution with a higher solute concentration compared with another solution.
How does concentration compare and contrast with solubility?
Substances of a higher concentration (or with higher level of water molecules) are more soluble than lower concentration liquids.
How did those substances go into the water outside the dialysis?
The substance moved into the water through osmosis. The concentration of the substances inside the dialysis bag was higher than in the water and membrane was permeable to the substances. As such, they moved from a high to a low concentration along a concentration gradient.
Why does water generally move in the opposite direction of dissolved substances?
Diffusion is the process of a substance moving from an area of a higher concentration to a lower concentration. In this scenario the dissolved substance is the higher concentration and the water would go to an area with the lower concentration.
Does some diffusion require energy?
No. Diffusion is a natural occurrence of the net movement of substances from a region of higher concentration to a region of lower concentration (down the concentration gradient).
A solution containing a higher concentration of dissolved substances than a cell is termed?
Hypertonic solution
What is diffusion in substances?
Concentration increases the number of molecules to pass through, hence the result.
What is the pathway of movement for substances traveling across a capillary wall?
Capillaries have very thin walls which are semi-permeable.
What name is given to the process by which substances pass into or out of a cell from an area of higher concentration to an area of lower concentration?
diffusion
During active transport substances move from regions of what?
in active transport, where do molecules always go
What type of work uses ATP to pump substances across membrane?
Various pumps use ATP to move substances across membranes. The pumps are often moving substance from a lower concentration to a higher. This movement is called "against the gradient" as movement usually moves from a higher concentration to a lower to even out the concentration. It takes energy to keep this. The pumps are mostly proteins.
How osmosis and diffusion are alike?
Answerdiffusion- movement of molecules from higher proportion to lower proportionosmosis - movement of water molecules from a more CONCENTRATED solution to less concentrated solution
Why do dissolved particles on one side of a membrane result in the diffusion of water across the membrane?
When one area has a higher concentration than another area substances move from the area of high concentration to the area of low concentration.
