The Concentrations of the Substances 'moves down' along the Gradient.
When a substance moves from a region where its more concentrated to where it is less.
Diffusion is an example of when ions move down a concentration gradient.
Diffusion moves down the concentration gradient because of the kinetic energy that drives diffusion entirely . A concentration gradient is the difference in the molecules across a distance .
When you move down a concentration gradient, you move from a location of greater concentration to a location of lesser concentration.

What is concentration gradient downhill or uphill?
A concentration gradient refers to the difference in solute concentration between two regions. When a solute moves from an area of higher concentration to lower concentration, it is moving "downhill" along the concentration gradient. In the reverse situation, where a solute moves from an area of lower concentration to higher concentration, it is moving "uphill" against the concentration gradient.
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!)
What moves up a concentration gradient and requires a carrier?
Passive transport involving facilitated diffusion moves particles up a concentration gradient and requires a carrier protein to facilitate the movement across the cell membrane. This process does not require energy input from the cell.
Where and when does diffusion occur?
Diffusion occurs when there is a concentration gradient i.e. a substance moves from higher to lower concentration.
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?
A substance that moves by passive transport tends to move down its concentration gradient, meaning from an area of high concentration to an area of low concentration. This process does not require the input of energy.
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.
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.
When a substance moves from an area of low concentration to an area of high concentration while using energy the processed is term is?
When a substance moves from an area of low concentration to an area of high concentration while using energy the process is called active transport.
What type of diffusion moves water down a concentration gradient through a semi permeable membrane?
Osmosis is the type of diffusion that moves water down a concentration gradient through a semi-permeable membrane. Water moves from an area of higher water concentration (lower solute concentration) to an area of lower water concentration (higher solute concentration).
Does Passive transport uses ATP to move molecules against their concentration gradient?
No, passive transport does not require ATP because it moves molecules along their concentration gradient, from an area of higher concentration to an area of lower concentration. ATP is only required for active transport, which moves molecules against their concentration gradient.
What is concentration gradient downhill or uphill?
A concentration gradient refers to the difference in solute concentration between two regions. When a solute moves from an area of higher concentration to lower concentration, it is moving "downhill" along the concentration gradient. In the reverse situation, where a solute moves from an area of lower concentration to higher concentration, it is moving "uphill" against the concentration gradient.
Does passive transport move from high concentration to low concentration?
Passive transport moves molecules from a high to low concentration gradient.
Term for the movement of substance against a concentration gradient?
