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.
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.
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.
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.
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.
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.
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.
In order for molecules to move against the concentration gradient?
Molecules can move against the concentration gradient through active transport, which requires energy input from ATP or an electrochemical gradient. In active transport, specific proteins pump molecules across the cell membrane, consuming energy to maintain a concentration gradient.

Active transport is used when molecules are moved across a cell membrane against their concentration gradient, from a low to a high concentration.
How is reverse osmosis similar to active transport?
Reverse osmosis is a form of active transport where water molecules are pushed through a semipermeable membrane against their concentration gradient, similar to how active transport uses energy to move molecules against their concentration gradient. Both processes require an input of energy to move molecules from an area of lower concentration to an area of higher 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.
What moves solutes against concentration gradient?
Active transport moves solutes against the concentration gradient by using energy, typically in the form of ATP, to pump molecules across a cell membrane. This process allows cells to maintain specific internal concentrations of molecules that may be higher or lower than the surrounding environment.
