What concentration gradient moves when a low concentration moves from an area of a higher concentration?
The concentration gradient is controlled by Diffusion. This same movement in reverse is known as Osmosis.
For diffusion to occur which condition must be met?
Diffusion occurs when a substance moves from an area of high concentration to an area of low concentration. This will happen naturarally without disruption, But is more common (and will happen faster) in a warm environment.
How is active transport different then osmosis?
Osmosis is the diffraction of water through a permeable membrane using no energy, whereas active transport is the moving of particles across a membrane against a concentration gradient. Basically, Osmosis moves water with no energy. Active transport moves particles, in general, with the use of chemical energy like ATP.
What substance moves by osmosis?
water
What happens when an electron moves from a low energy state to a high energy state?
when an electron moves from low energy state to high energy state , it gains energy.
When a substance moves from an area of low concentration to an area of high concentration while using energy the proces is termed what?
active transport
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 substance that moves across a cell membrane without using the cell's energy tends to move?
from an area of low concentration to an area of high concentration (if it is water) the opposite if it is a solid
How does facilitate transport differ from active transport?
Facilitated transport occurs when a substance moves from an area of higher concentration to an area of lower without the aid of energy. Active transport involves additional energy as it is moving from a lower concentration into a higher concentration.
What is the process by which a substance moves from a level of higher concentration to a level of lower concentration?
Osmosis
Where and when does diffusion occur?
Diffusion occurs when there is a concentration gradient i.e. a substance moves from higher to lower concentration.
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!)
When water moves through an area of higher concentration to lower concentration?
When a region of higher concentration to a region of Lower concentration against the gradient which requires Energy is called 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 is the passive transportation of substances across the cell membrane called?
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 best describes passive transport?
it moves materials from areas of high concentration to areas of low concentrationit moves materials of high concentration to areas of low concentration
What is the difference between facilitated diffusion with the help of a carrier protein and active transport with the help of a transport protein?
Facilitated diffusion is a type of passive transport in which a substance moves across the cell membrane from high to low concentration. In this situation, the substance moves with the concentration gradient, and with the help of carrier molecules, it is able to make it's way across the membrane smoothly and without the expense of energy. Active transport, on the other hand, is the movement of a substance across the cell membrane from low to high concentration, making the transport a bit more difficult and calling for the use of energy. Transport proteins recognize the substance and allow it to cross through the membrane.
