How do molecules move down a concentration gradient?
Molecules move down a concentration gradient through a process called diffusion. This means that molecules naturally move from an area of high concentration to an area of low concentration until they are evenly distributed. This movement occurs due to the random motion of molecules and does not require energy input.
What types of transport moves molecules along a concentration gradient?
I'm not sure you're understanding the question you are asking. Molecules are the tiny building blocks, made up of atoms, that are used to create everything in our galaxy. Cells are a single living unit that work together to be a living thing. If you are interested in how parts of a cell move around or pass along material, you should look up how cells work or ask a more specific question.
What happens when there is no concentration gradient?
When there is no concentration gradient, there is no net movement of particles from one area to another. This means that the particles are evenly distributed in the system, leading to a state of equilibrium where there is no further movement of particles.
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.
Does a cell use energy when molecules diffuse in or out of the cell down the concentration gradient?
Diffusion is passive transport - it means that the cell doesn't use any energy transporting the materials. However, if there is more of a substance inside a cell than outside a cell (like nutrients), and the cell needs to get the nutrients in, diffusion will not owrk. The cell uses energy to do active transport and get the particles in.
What is primary active transport?
Primary active transport is defined as utilizing energy in the form of ATP to transport molecules across a membrane against their concentration gradient. This means moving from a low concentration to a high concentration.
Which process do oxygen molecules move down a concentration gradient?
Oxygen molecules move down a concentration gradient through simple diffusion. This means they move from an area of higher concentration to an area of lower concentration until equilibrium is reached.
What does it means if a substance moves down its concentration gradient?
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.
How do molecules move down a concentration gradient?
Molecules move down a concentration gradient through a process called diffusion. This means that molecules naturally move from an area of high concentration to an area of low concentration until they are evenly distributed. This movement occurs due to the random motion of molecules and does not require energy input.
Is the rate of diffusion in a steeper concentration gradient slower than in a shallow concentration gradient?
No, the rate of diffusion is faster in a steeper concentration gradient compared to a shallow one. A steeper gradient means there is a larger difference in concentration between two areas, which drives molecules to move more quickly from the area of higher concentration to the area of lower concentration. Conversely, a shallow gradient has a smaller difference, resulting in a slower diffusion rate.
Diffusion continues until there is no?
Diffusion continues until there is no longer a concentration gradient present between the two regions. Once equilibrium is reached, the molecules will be evenly distributed throughout the system and diffusion will stop.
Explain what a concentration gradient is and what it means for a molecule to diffus down its concentration gradient?
If you carefully put a drop of food coloring in a large container, you will notice that it will begin to move away from the place where the drop began. It actually, over a long time, it will diffuse all through the container. If the container is very large you may not even see the color any more. Since it moves away from the main drop, it is moving down the concentration gradient.
What does net diffusion?
Net diffusion means the total diffusion due to both holes & electrons .
Does active transport move from higher to lower concentration?
Active Transport- When molecules move from an area of lower concentration to an area of higher concentrationPassive Transport- When molecules move from an area of higher concentration ot an area of higher concentration (also called diffusion)

What is the relationship between a concentration gradient and the rate of diffusion?
the concentration gradient is about both active and passive transport equilibrium is when the is no concentration gradient but equilibrium is a transient condition this is because molecules are in constant random motion the electrons spinning around the molecule's nucleus keep them in random motion since they're in random motion they constantly bump into each other since the constantly bump into each other they try to spread out this describes the force of diffusion so, when the molecules are bunched together they have high concentration they'll try to spread out, which moves them to lower concentration this means they have moved down the concentration gradient it is passive transport because these was no energy used to make it happen as long as the molecules are small enough in other words as long as there's no large molecules dissolved in the solution then the solution and its solutes are free to diffuse but any large molecules dissolved in the solution will not pass through a semipermeable membrane
What are two major means of active membrane transport?
Two major means of active membrane transport are primary active transport, which directly uses energy in the form of ATP to transport molecules against their concentration gradient, and secondary active transport, which uses the energy stored in the electrochemical gradient of one molecule to drive the transport of another molecule against its gradient.
