Is the movement of molecules across a membrane down the concentration gradient a passive or active process?
The movement of molecules across a membrane down the concentration gradient is a passive process.
What is the process that occurs when molecules move from an area of low concentration to an area of high concentration, against the concentration gradient?
The process that occurs when molecules move from an area of low concentration to an area of high concentration, against the concentration gradient, is called active transport. This process requires energy to pump molecules across the cell membrane.
How do molecules move along a concentration gradient?
Molecules move along a concentration gradient through a process called diffusion, where they naturally flow from areas of high concentration to areas of low concentration until equilibrium is reached.
How does the process of active transport move molecules up the concentration gradient?
Active transport moves molecules up the concentration gradient by using energy from ATP to pump molecules against the natural flow, from an area of low concentration to an area of high concentration. This process requires specific transport proteins in the cell membrane to actively move the molecules.
Proceeds Against a concentration Gradient requires a carrier?
Yes, the movement of molecules against a concentration gradient requires the use of a carrier protein or active transport mechanism in order to transport the molecules from an area of lower concentration to an area of higher concentration. This process requires energy to move molecules against their natural gradient.

Diffusion is the process of movement of molecules under a concentration gradient?
Yes
How do molecules move along a concentration gradient?
Molecules move along a concentration gradient through a process called diffusion, where they naturally flow from areas of high concentration to areas of low concentration until equilibrium is reached.
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.
Which process do oxygen molecules move down a concentration gradient?
Oxygen molecules move down a concentration gradient through simple diffusion. This means they move from an area of higher concentration to an area of lower concentration until equilibrium is reached.
How does the process of active transport move molecules up the concentration gradient?
Active transport moves molecules up the concentration gradient by using energy from ATP to pump molecules against the natural flow, from an area of low concentration to an area of high concentration. This process requires specific transport proteins in the cell membrane to actively move the molecules.
Proceeds Against a concentration Gradient requires a carrier?
Yes, the movement of molecules against a concentration gradient requires the use of a carrier protein or active transport mechanism in order to transport the molecules from an area of lower concentration to an area of higher concentration. This process requires energy to move molecules against their natural gradient.
Is Diffusion is the process by which molecules move from areas of lower concentration to areas of higher concentration?
No, diffusion is the process by which molecules move from areas of higher concentration to areas of lower concentration in order to reach equilibrium. It is a passive process driven by the concentration gradient.
How can molecules move against the concentration gradient and reach equilibrium?
Molecules can move against the concentration gradient through active transport, which requires energy input. This process allows molecules to be transported from an area of lower concentration to an area of higher concentration, ultimately reaching equilibrium through the continuous movement of molecules.
Why active transport requires energy?
Active transport requires energy because it moves molecules or ions against their concentration gradient, from areas of lower concentration to areas of higher concentration. This process goes against the natural tendency of molecules to diffuse down their concentration gradient, requiring the input of energy in the form of ATP to drive the transport proteins involved.
How do molecules move down a concentration gradient?
Molecules move down a concentration gradient through a process called diffusion. This means that molecules naturally move from an area of high concentration to an area of low concentration until they are evenly distributed. This movement occurs due to the random motion of molecules and does not require energy input.
