To move substances from low to high concentration.
What else can I help you with?
Does active transport move molecules against the concentration gradient?
Yes, active transport moves molecules against the concentration gradient.
What id the difference between active and passive transport?
Active transport requires energy to move molecules against their concentration gradient while passive transport does not require energy and moves molecules from high to low concentration. Active transport is selective and can transport specific molecules, while passive transport is nonselective and moves molecules based on their 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.
Does active transport involve the movement of molecules against the concentration gradient?
Yes, active transport involves the movement of molecules against the concentration gradient.
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.
What is moved by active transport?
Molecules are moved by active transport.
Does active transport move molecules against the concentration gradient?
Yes, active transport moves molecules against the concentration gradient.
Does active transport result in an even distribution of molecules?
No. Active transport uses energy to transport specific molecules against a concentration gradient. Passive transport will result in an even distribution of molecules because they allow molecules to move down a concentration gradient.
What id the difference between active and passive transport?
Active transport requires energy to move molecules against their concentration gradient while passive transport does not require energy and moves molecules from high to low concentration. Active transport is selective and can transport specific molecules, while passive transport is nonselective and moves molecules based on their 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.
Does active transport involve the movement of molecules against the concentration gradient?
Yes, active transport involves the movement of molecules against the concentration gradient.
What is the Method of movement that requires the expenditure of ATP molecules is?
The movement that requires the expenditure of ATP molecules is called active transport. In active transport, cells use ATP to move molecules or ions against their concentration gradient, ensuring that specific substances are taken up or expelled from the cell as needed. This process is essential for maintaining cellular functions and homeostasis.
When active transport used to move molecules what is required?
Active transport requires energy, typically derived from ATP, to move molecules against their concentration gradient. This process involves specific transport proteins or pumps in the cell membrane that facilitate the movement of substances into or out of the cell. Unlike passive transport, which relies on concentration differences, active transport allows cells to maintain essential concentrations of ions and nutrients necessary for various cellular functions.
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
What is the source of the energy used in active transport?
The energy used in active transport is derived from ATP (adenosine triphosphate), which is produced through cellular respiration in the mitochondria of cells. ATP provides the necessary energy for the transport proteins to move molecules against their concentration gradient across the cell membrane.
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.
How does facilitated transport differ from active transport in terms of the energy requirements and mechanisms involved in moving molecules across a cell membrane?
Facilitated transport and active transport are two ways molecules can move across a cell membrane. Facilitated transport does not require energy from the cell, while active transport does require energy in the form of ATP. Facilitated transport uses carrier proteins to help molecules move across the membrane, while active transport uses pumps to move molecules against their concentration gradient.
