There are two processes, Exokineses and Endokineses. just to make sure, go to Biology-online.org Then type in these scientific names and see if they're right. TY

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.


How might a cell overcome a concentration gradient?

A cell can overcome a concentration gradient by using active transport mechanisms such as pumping ions or molecules against their concentration gradient. This requires energy in the form of ATP to move molecules from an area of low concentration to an area of high concentration. Additionally, cells can also utilize facilitated diffusion where integral membrane proteins help transport molecules down their concentration gradient.


Which proteins are used in active and passive transport?

In active transport, proteins like pumps (such as Na+/K+ ATPase) are commonly used to move molecules against their concentration gradient, requiring energy in the form of ATP. Passive transport commonly involves proteins like ion channels and carrier proteins that facilitate the movement of molecules down their concentration gradient without requiring energy input.


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.

Does active transport move molecules against the concentration gradient?

Yes, active transport moves molecules against the concentration gradient.


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 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.


Differences between active transport and facilitated diffusion?

Active transport requires energy in the form of ATP to move molecules against their concentration gradient, while facilitated diffusion uses carrier proteins to move molecules down their concentration gradient without requiring energy. Active transport can move molecules against their concentration gradient, while facilitated diffusion can only move molecules down their concentration gradient.

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.


What proteins are used in both active and passive transport?

Transport proteins such as ion channels and carrier proteins are used in both active and passive transport processes. Ion channels move ions down their concentration gradient through passive transport, while carrier proteins can facilitate passive transport by allowing molecules to move along their concentration gradient, or active transport by requiring energy to transport molecules against their concentration gradient.


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.
