If a substance moves down its concentration gradient, it means that it is moving from an area where it has a high concentration to an area where it has a low concentration. This is known as diffusion.

When a substance moves from an area of low concentration to an area of high concentration the substance moves its concentration gradient?

When a substance moves from an area of low concentration to an area of high concentration, it is moving against its concentration gradient. This process typically requires energy, as it is not a passive movement. Such transport mechanisms include active transport, where cellular energy (like ATP) is used to facilitate the movement. In contrast, substances usually move from high to low concentration naturally, which is known as moving down the concentration gradient.


What is concentration gradient downhill or uphill?

when the solute passes from a higher solute concentration to a lower solute concentration, it is known as concentration gradient downhill. and the reverse is true for uphill. also, down hill transport requires energy which is derived from ATP. uphill transport is not derived from ATP's rather from the random motion of the molecules themselves.


What is the transport that moves a solute down the concentration gradient?

Simple diffusion


What moves up a concentration gradient?

its active transport because it expands in opp direction and pushes


How is the active transport different from diffusion?

The main difference is that diffusion does not require energy and active transport does require energy. Just for the record diffusion has a concentration that moves from high to low, and active transport has a concentration that moves from low to high. (Hope this helps to answer your question!)

Where and when does diffusion occur?

Diffusion occurs when there is a concentration gradient i.e. a substance moves from higher to lower concentration.


What moves against the concentration gradient in biological systems?

In biological systems, active transport moves substances against the concentration gradient.


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.


A substance that moves by passive transport tends to move where?

Passive transport means it does not require energy. Therefore, substances move from areas of high concentration to low concentration. They do not require energy because they are staying within the concentration gradient.


Does passive transport move with or against the concentration gradient?

Passive transport moves with the concentration gradient.


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.


What is necessary for simple diffusion?

For simple diffusion to occur, a concentration gradient must exist where a substance moves from an area of higher concentration to an area of lower concentration. Additionally, the cell membrane must be permeable to the substance diffusing, allowing it to pass through freely.


Does passive transport move substances with the concentration gradient?

Yes, passive transport moves substances with the concentration gradient.


What concentration gradient moves when a low concentration moves from an area of a higher concentration?

The low concentration moves down its concentration gradient from an area of high concentration to an area of low concentration. This process is driven by diffusion, where particles move spontaneously from regions of high concentration to regions of low concentration until equilibrium is reached.


Does facilitated diffusion move with or against the concentration gradient?

Facilitated diffusion moves molecules with the concentration gradient, from an area of high concentration to an area of low concentration.


Does passive transport move up or down the concentration gradient?

Passive transport moves down the concentration gradient, from an area of higher concentration to an area of lower concentration.


Does active transport move molecules against the concentration gradient?

Yes, active transport moves molecules against the concentration gradient.
