When you have one concentration (amount) of a molecule, connected to a higher or lower concentration through a permeable membrane (bridge), there is a natural force (heat) pushing the molecules to go from the higher concentration to the lower concentration until both sides have balanced (it is also called diffusion, this process is related to the laws of thermodynamics).
Anyway this force the measurement of force for this movement is called the concentration gradient.
For a molecule to move against this natural force is to against the concentration gradient, it requires an energy GREATER then that from diffusion or heat to push it.
An example would be when there is an opposing electrical force strong enough that may push an electrically charged molecule against its concentration gradient.
What else can I help you with?
Proceeds Against a concentration Gradient requires a carrier?
Yes, the movement of molecules against a concentration gradient requires the use of a carrier protein or active transport mechanism in order to transport the molecules from an area of lower concentration to an area of higher concentration. This process requires energy to move molecules against their natural gradient.
Does osmosis work with or against the concentration gradient?
Osmosis works with the concentration gradient, meaning that it involves the movement of water molecules from an area of low solute concentration to an area of high solute concentration in order to equalize the solute concentration on both sides of the membrane.
What is the transport of materials against a concentration gradient called?
The process of moving materials against a concentration gradient is called active transport. Active transport generally uses a protein pump to move molecules from an area of low concentration to an area of high concentration; in order to perform an active transport, the cell must use some of its energy to initiate the reaction.
What is the type of transport in which a cell goes against the concentration gradient in order to diffuse substances within?
Active transport is the type of transport in which a cell moves substances against their concentration gradient, requiring energy to do so. This process helps maintain the internal balance of substances within the cell.
During diffusion molecules tend to move?
AnswerParticles move from regions of higher concentration to regions of lower concentration because of the concentration gradient,they move down gradient i.e from high to low concentration

Is Diffusion is the process by which molecules move from areas of lower concentration to areas of higher concentration?
No, diffusion is the process by which molecules move from areas of higher concentration to areas of lower concentration in order to reach equilibrium. It is a passive process driven by the concentration gradient.
Molecules move in and out freely from high to low concentration?
This process is called simple diffusion, where molecules passively move down their concentration gradient, from an area of high concentration to an area of low concentration, in order to achieve equilibrium. This is a fundamental mechanism for the movement of small non-polar molecules across a cell membrane.
Does active transport require transport proteins?
Yes, active transport does require transport proteins. These proteins use energy to move molecules against their concentration gradient, typically from an area of low concentration to high concentration. This process is essential for maintaining cellular homeostasis.
In order for a cell in a culture to obtain glucose the concentration of glucose must be?
In order for a cell in a culture to obtain glucose, the concentration of glucose must be higher outside the cell than inside. This concentration gradient allows for the process of diffusion, where glucose molecules move passively into the cell. Additionally, if the glucose concentration outside the cell is low, cells may require active transport mechanisms to uptake glucose against the gradient. Overall, maintaining an adequate external glucose concentration is crucial for cellular metabolism and energy production.
Which cell transport process requires cell energy?
Simply because these substances are going against the gradient of concentration; from low concentration to high concenration. For example: in order to get to the top of the mountain (high concentration) you need to spend energy (ATP`s) climbing from the bottom (low concentration).
How is active transport similar to facilitated diffusion?
Active transport and facilitated diffusion both involve the movement of molecules across a cell membrane. However, active transport requires energy in the form of ATP to move molecules against their concentration gradient, while facilitated diffusion uses carrier proteins to move molecules along their concentration gradient without requiring energy.
What mechanism does a cell use to move small potassium molecules into the cell against the concentration gradient?
To transport any molecules against a concentration gradient, ATP is required. This process is called active transport. Active transport is enabled by carrier proteins which are located in the cell membrane. To transport charged molecules through the membrane, pore proteins are required.
