Do chemical substance move from areas of high concentration to areas of low concentration as they pass in and out of a cell?
Yes, chemical substances typically move from areas of high concentration to areas of low concentration through a process called diffusion. This movement occurs to achieve equilibrium and is a fundamental principle of cellular transport. In the context of cells, this process is vital for the exchange of nutrients and waste products, allowing cells to maintain homeostasis. Additionally, certain transport mechanisms, like facilitated diffusion, help specific molecules move across cell membranes following this concentration gradient.
What else can I help you with?
When there are different amounts of a substance on either side of the cell membrane what gradient results.?
It is known as a concentration gradient which in diffusion will always flow from areas of high concentration to areas of lower concentrations.
When there are different amounts of a substance on either side of the cell membrane an gradient results?
osmosis
What is the state a substance is in when the concentration of the substance is the same on both sides of a cell membrane?
isotonic
What process moves materials through a cell areas of low concentration to areas of high concentration?
active transport
If substance A could defuse across the membrane what would happen to the concentration of A inside the cell and outside the cell?
If substance A can diffuse across the membrane, it will move from an area of higher concentration to an area of lower concentration until equilibrium is reached. This means that the concentration of A inside the cell will increase while the concentration outside the cell will decrease, assuming that the initial concentration outside the cell is higher than inside. Eventually, the concentrations inside and outside the cell will become equal if no other factors interfere.

When is a substance most likely to diffuse into a cell?
If there is the concentration of substance inside the cell is lesser than outside and cell membrane is permeable to the substance.
What does concentration gradient have to do with diffusion of substances across the cell membrane?
The concentration gradient refers to the difference in concentration of a substance between two regions. In the context of cell membranes, substances tend to move from areas of higher concentration to areas of lower concentration to reach equilibrium. This movement is known as diffusion and it is driven by the concentration gradient.
While conducting an experiment you discover a certain substance passing out of a cell by diffusion what might you conclude about the concentration of this substance?
If a substance is passing out of a cell by diffusion, it suggests that the concentration of the substance is higher inside the cell than outside. This movement is driven by the substance's tendency to move from an area of higher concentration to an area of lower concentration to reach equilibrium.
What is cells solution in which the concentration of dissolved substance in the solution is the same as concentration of dissolved substance inside a cell?
isotonic

osmosis
Does the cell potential change with concentration variations in a chemical reaction?
Yes, the cell potential can change with concentration variations in a chemical reaction. This is because the concentration of reactants and products can affect the flow of electrons in the cell, which in turn influences the cell potential.
