A diffusion gradient exists in tissues due to differences in concentration of substances. This gradient drives the passive movement of molecules from areas of higher concentration to areas of lower concentration, allowing cells to obtain necessary nutrients and get rid of waste products.
What else can I help you with?
If diffusion is going to occur there has to be what?
A difference in the concentration throughout space because diffusion doesn't just happen in a cell or aqueous solution by definition diffusion is just from high to low concentration
What is the transport that moves a solute down the concentration gradient?
Simple diffusion
Where do diffusion molecules move?
Down the concentration gradient
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.
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.
Why is diffusion affected by a decrease in concentrated gradient?
Diffusion is affected by a decrease in concentration gradient because concentration gradient is directly proportional to the rate of diffusion. A decrease in concentration gradient also lowers the rate of diffusion.
If diffusion is going to occur there has to be what?
A difference in the concentration throughout space because diffusion doesn't just happen in a cell or aqueous solution by definition diffusion is just from high to low concentration
How diffusion will occur?
diffusion is occur when different concentration gradient is applied
What must there be for diffusion to occur?
a gradient
Concentration gradient has to do with diffusion?
Yes it does.
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.
What is A true statement about diffusion?
The greater the concentration gradient, the faster the rate of diffusion.
What is true statements about diffusion?
The greater the concentration gradient, the faster the rate of diffusion.
Diffusion gradient for oxygen between the alveoli and the pulmonary capillaries?
The diffusion gradient for oxygen between the alveoli and the pulmonary capillaries is driven by the difference in partial pressures of oxygen (pO2) in these two compartments. In the alveoli, the pO2 is higher due to fresh air being inhaled, while in the pulmonary capillaries, the pO2 is lower because oxygen has been utilized by the body's tissues. This gradient facilitates the passive diffusion of oxygen from the alveoli into the blood, allowing for efficient gas exchange and oxygenation of the blood. The process continues until equilibrium is reached, ensuring that oxygen is delivered to tissues throughout the body.
Is diffusion quicker when there is a higher concentration gradient?
Yes, diffusion is quicker when there is a higher concentration gradient because it drives the movement of molecules from areas of higher concentration to areas of lower concentration more rapidly. The steeper the concentration gradient, the faster the rate of diffusion.
What is an example of diffusion in a sentence?
The rate of diffusion is determined by the permeability of the membrane and the concentration gradient.
What is the transport that moves a solute down the concentration gradient?
Simple diffusion
