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.

What type of transportation requires energy to move a molecule?
Active transport requires energy to move molecules across a cell membrane, typically against a concentration gradient. This process is vital for maintaining proper internal conditions within a cell. Examples of active transport mechanisms include pumps and vesicular transport.
Why active transport is a energy dependent process?
Active transport relies on cellular energy in the form of adenosine triphosphate (ATP) to pump molecules against their concentration gradient across the cell membrane. This process requires energy to overcome the natural tendency of molecules to move from high to low concentration, ensuring the cell can maintain the desired internal environment.
How can active transport differ from passive transport?
Active transport requires energy input to move molecules against their concentration gradient, while passive transport does not require energy and moves molecules along their concentration gradient. Active transport usually involves the use of transport proteins, such as pumps or carriers, while passive transport relies on diffusion or facilitated diffusion.
Is facilitated diffusion an example of active transport?
No, facilitated diffusion is a type of passive transport where molecules move across a cell membrane with the help of transport proteins. Active transport, on the other hand, requires energy to move molecules against their concentration gradient.
What is the cellular movement of a substance that requires the use of energy.?
Active transport is the cellular movement of a substance that requires the use of energy. This process involves the movement of molecules across a cell membrane against their concentration gradient, requiring the cell to expend energy in the form of ATP. Active transport allows cells to control the internal environment and maintain homeostasis.
Transport which requires energy?
active
How is active transport different then then other types of cell transport?
active transport requires input of energy as it takes place aginst a gradient.
What is differs between active transport and passive transport?
Active transport requires energy; passive transport does not.
The difference between active transport and passive transport is?
Active transport requires energy; passive transport does not.
How does active transport differ from passive transport-?
Active transport requires energy while passive transport does not.
What type of transport requires energy to move molecule?
Active transport requires energy to move a molecule.
What kind of transport needs energy?
active transport requires energy from the cell
What does not describe passive transport?
Active transport requires energy.
How did active transport get its name?
its name is due to the fact that active transport requires energy as opposed to passive transport when no energy is required.
What is the dif frence between active and passive transport?
Active transport requires energy, passive transport does not.
Does active or passive transport by engulfing?
it is active because it requires energy
How do passive and active transport differ?
yyou momm a is ugly
