The textbook definition of "passive transport" is moving from high to low concentration.
You mean passive diffusion..

How is the concentration gradient of a substance important to diffusion?
In diffusion, substances flow with a concentration gradient, meaning that they flow from areas of high concentration to areas of lower concentration. Flowing against a concentration gradient would be going from an area of low concentration to an area of higher concentration, but this only occurs in active transport.
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 is process that moves molecules across a cell membrane from regions of lower concentration to higher concentration?
The process that can move molecules from a low to a high concentration through a cell membrane is active transport.
What is the movement of a substance from an area of high concentration to an area of low concentration?
passive transport Movement down a concentration gradient is known as diffusion.
What proceeds against a concentration gradient?
Molecules can move against concentration gradient by a movement called active transport. Molecules move from an area of low concentration to an area of high concentration by using chemical energy called ATP or an electrochemical gradient--either way, it uses cellular energy.
What transport that requires no energy and moves substances from an area of high concentration to a lower concentration?
Your mom...........no I'm just kidding, but there are some cars that regire no energy, but just solar power.
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)
The net movement of water across a membrane from the solution of lower concentration to one of higher concentration is called?
This is referred to as OSMOSIS. When you say "solution of lower concentration" this implies the solute concentration is low, thus water concentration is high. So, osmosis is movement of water from a high concentration of water, to a lower concentration of water, just to be clear.
When do cells do active transport?
When transporting substances from low to high concentration, or when transporting substances too large to pass through the membrane without assistance from a transport protein.
How is the concentration gradient of a substance important to diffusion?
In diffusion, substances flow with a concentration gradient, meaning that they flow from areas of high concentration to areas of lower concentration. Flowing against a concentration gradient would be going from an area of low concentration to an area of higher concentration, but this only occurs in active transport.
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.
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
What type of transport is used to move a molecule from a region of low concentration to a region of high concentriation?
Active transport moves an object from an area of lower concentration to an area of higher concentration. When the reverse is true, passive transport suffices.
What is the movement of solute from a region of high concentration to one of lower concentration?
Diffusion; a form of passive transport.
What is passive transpot?
Passive transport is the movement of substances across a cell membrane without the use of energy. It occurs along a concentration gradient, with substances moving from an area of high concentration to an area of low concentration. Examples include diffusion and facilitated diffusion.
The movement of particals from areas of high concentration to areas of low concentration is called?
Diffusion is the movement of particles from an area of high concentration to an area of lower concentration. Active transport is the movement of substances from lower to higher concentration across a semi permeable membrane that must have a specific protein carrier and cell expenditure of energy.
Does passive transport move from high concentration to low concentration?
Passive transport moves molecules from a high to low concentration gradient.
