A high concentration gradient means that the concentration of a substance is?
It means one side have high concentration.Other side has lower.
What is the type of transport in which a cell goes against the concentration gradient in order to diffuse substances within?
Active transport is used to move molecules and ions across a membrane against their concentration gradient. "Active" means that the transporter requires energy to do its job (eg. glucose).
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 is active transport and passive transport?
active transport requires the use of energy aka ATP and is usually against the concentration gradient. passive transport does not require energy because it moves in response to the concentration gradient.
What direction are substances said to diffuse?
if something diffuses e.g. particles through the air or CO2 out of body cells means the particles go from a high concentration to a low concentration
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.
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.
A high concentration gradient means that the concentration of a substance is?
It means one side have high concentration.Other side has lower.
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.
Diffusion continues until there is no?
Concentration gradient. After there's no concentration gradient, equilibrium occurs, which means no more diffusion.
What is the type of transport in which a cell goes against the concentration gradient in order to diffuse substances within?
Active transport is used to move molecules and ions across a membrane against their concentration gradient. "Active" means that the transporter requires energy to do its job (eg. glucose).
For diffusion to occur there must be?
For diffusion to occur there needs to be a concentration gradient. Which means that the concentrations on the two sides must be different. In diffusion the particles flow from high concentration to low concentration.
Description of osmosis?
osmosis means the movement of water from a high concentration gradient to a low concentration gradient, through a SEMI-permable membrane, osmosis is 'complete' whene both sides are in they state of equalibrium this means when the water molecules are evenly spread out. e.g. a potato clyinder in a water beaker, the water particles in the potato is greater than in the beaker of water, and so as the definition says '...from a high to low concentration...' the water molecules transferr from the potato to the beaker of water. If you don't get it ur dumb
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 happens in a cell transportation lab report?
When a cell membrane is said to be selectively permeable, it means that the cell membrane controls what substances pass in and out through the membrane. This characteristic of cell membranes plays a great role in passive transport. Passive transport is the movement of substances across the cell membrane without any input of energy by the cell. The energy for passive transport comes entirely from kinetic energy that the molecules have. The simplest type of passive transport is diffusion, which is the movement of molecules from an area of high concentration to an area of lower concentration. Diffusion moves down the concentration gradient, which is the difference in the concentration of molecules across a space. Osmosis is a type of diffusion in which water molecules move down the concentration gradient. When the concentration of solute molecules outside the cell is lower than the concentration of solute in the cytosol , the solution outside is hypotonic to the cytosol. If the concentration of solute molecules is higher outside of the cell, the solution outside is said to be hypertonic. The solution outside is isotonic if the concentration is equal on both sides of the cell membrane.
