Are molecules spread out in high concentration?
This spread of particles through random motion from an area of high concentration to an area of lower concentration is known as diffusion. This unequal distribution of molecules is called a concentration gradient. Once the molecules become uniformly distributed, dynamic equilibrium exists.
Do molecules flow from low to high concentration?
Molecules move from an area of high concentration to an area of lower concentration until an equilibrium is met. The molecules continue to cross the membrane at equilibrium, but at equal rates in both directions.
Is diffusion from high to low or low to high?
Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration.
When a molecule moves from low concentration to high concentration?
Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. For cell transport, diffusion is the movement of small molecules across the cell membrane.
What is the spread of molecules?
Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. The difference in the concentrations of the molecules in the two areas is called the concentration gradient.
When molecules spread from an area of high to low concentration to it is called?
Diffusion is a process of passive transport in which molecules move from an area of higher concentration to one of lower concentration.
When molecules move from a low to high concentration it is called moving the concentration gradient?
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
How does a molecule move down the concentration gradient?
A molecule moves down its concentration gradient using a transport protein in the plasma membrane. This is an example of Nice work! You just studied 71 terms! Now up your study game with Learn mode.
How does a molecule move across the plasma membrane?
molecules move across the plasma membrane against their concentration gradient. A molecule moves down its concentration gradient using a transport protein in the plasma membrane. This is an example of through facilitated diffusion or diffusion.
Which is the substance that diffuses farthest?
Since substance #4 has the lowest molecular weight, it will move faster than the other substances. Substance #4 will diffuse farthest because the molecular weight is least. a. diffusion.
What is the difference between diffusion and osmosis?
Diffusion is the movement of particles (ions or molecules) from an area of higher concentration to an area of lower concentration. Osmosis is the diffusion of water from a hypotonic solution into a hypertonic solution across and selectively permeable membrane.
