JordanActive transport is the process that drives molecules across a membrane against a concentration gradient, requiring energy input in the form of ATP. This process allows cells to accumulate substances they need in higher concentrations than their surroundings.

What is the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
When would active transport be used by a cell?
Active transport is used when molecules are moved across a cell membrane against their concentration gradient, from a low to a high concentration.
How can a cell transport a substance from lower to higher concentration?
A cell can transport a substance from lower to higher concentration through active transport, which uses energy to move molecules against the concentration gradient. This process typically involves the use of specialized proteins in the cell membrane to pump the molecules against the concentration gradient.
Which way do molecules move during active transport?
Molecules move against their concentration gradient, from an area of low concentration to high concentration, in active transport. This process requires energy input to pump the molecules across a membrane using specific proteins like pumps or carriers.
Molecules move from an area of low concentration to an area of high concentration during?
Active transport. This process requires energy to move molecules against their concentration gradient, typically through the use of transport proteins in the cell membrane.
Does osmosis work with or against the concentration gradient?
Osmosis works with the concentration gradient, meaning that it involves the movement of water molecules from an area of low solute concentration to an area of high solute concentration in order to equalize the solute concentration on both sides of the membrane.
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.
Does active transport move molecules against the concentration gradient?
Yes, active transport moves molecules against the concentration gradient.
Is osmosis with or against concentration gradient?
Osmosis is with the concentration gradient, meaning that it involves the movement of water molecules from an area of low solute concentration to an area of high solute concentration across a semi-permeable membrane.
Compare and contrast active transport and facilitated diffusion-?
Active transport requires energy input to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to move molecules down their concentration gradient. Both processes involve the use of proteins to transport molecules across the cell membrane, but active transport can move molecules against their concentration gradient, while facilitated diffusion can only move molecules down their concentration gradient.
Does active transport involve the movement of molecules against the concentration gradient?
Yes, active transport involves the movement of molecules against the concentration gradient.
Is active transport able to move molecules against the concentration gradient?
Yes, active transport is able to move molecules against the concentration gradient.
How are facilitated diffusion and active transport different in terms of their mechanisms of transporting molecules across the cell membrane?
Facilitated diffusion uses transport proteins to move molecules across the cell membrane with the concentration gradient, while active transport requires energy to move molecules against the concentration gradient.
What is the process that requires cellular energy to move a substance against its concentration gradient?
Active transport is the process that requires cellular energy to move a substance against its concentration gradient. This process uses ATP to pump molecules across the cell membrane, creating a concentration gradient where the molecule is more concentrated on one side of the membrane than the other.
How do cells transport molecules against their concentration gradient?
Cells transport molecules against their concentration gradient through a process called active transport. This process requires energy in the form of ATP to move molecules from an area of low concentration to an area of high concentration. Proteins embedded in the cell membrane, such as pumps and carriers, help facilitate this movement.
The transport of a substance across the cell membrane against its concentration gradient is called what?
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
How does active transport enable the movement of molecules against their concentration gradient?
Active transport enables the movement of molecules against their concentration gradient by using energy from ATP to pump the molecules across the cell membrane. This process allows the cell to maintain a higher concentration of certain molecules inside the cell compared to outside, which is necessary for various cellular functions.
