Is movement of a substance down its concentration gradient a passive transport?
Yes, movement of a substance down its concentration gradient is considered passive transport because it does not require energy expenditure by the cell. The substance moves from an area of high concentration to an area of low concentration through processes like simple diffusion, facilitated diffusion, or osmosis.
The movement of a substance from where there is large amounts and low amounts?
This is called diffusion. Substances move randomly, from an area of high concentration to an area of low concentration. Osmosis is a specific type of diffusion that only involves the random movement of water.
How is the concentration gradient of a substance important to diffusion?
In diffusion, substances flow with a concentration gradient, meaning that they flow from areas of high concentration to areas of lower concentration. Flowing against a concentration gradient would be going from an area of low concentration to an area of higher concentration, but this only occurs in active transport.
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.
When the concentration of a substance differs from one area to another this is called concentration?
This is called a concentration gradient, which represents the difference in concentration of a substance between two locations. The substance will naturally move down the concentration gradient from areas of higher concentration to lower concentration through processes like diffusion or active transport.
How does a polar substance get across a cells plasma membrane without the expenditure of energy assuming it is more concentrated outside if the cell?
A polar substance can cross a cell's plasma membrane through facilitated diffusion, which does not require energy expenditure. In this process, specific transport proteins help the polar substance move down its concentration gradient from an area of higher concentration to an area of lower concentration. This movement occurs until equilibrium is reached.

The substance moves from an area of high concentration to an area of low concentration through processes like simple diffusion, facilitated diffusion, or osmosis.
How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
A concentration gradient of a substance drives the movement of that substance from an area of high concentration to an area of low concentration. The steeper the concentration gradient, the faster the movement of the substance, requiring less energy to transport it. If the concentration on both sides of the gradient is equal, there is no net movement of the substance.
Movement of a substance down the substance's concentration gradient?
diffusion
Where and when does diffusion occur?
Diffusion occurs when there is a concentration gradient i.e. a substance moves from higher to lower concentration.
