Energy for primary active transport comes from ATP molecules. ATP is produced by the mitochondria. e.g. Na+/K+ ATPases are archetypal primary active transporters and they transport 3 Na+ ions out of cells and 2 K+ ions into cells by hydrolyzing one molecule of ATP. Energy for secondary active transport is stored in an established concentration gradient of ions across the cell membrane and drives transport with the tendency of ions to move from an area of high concentration to an area of lower concentration. e.g. Na+/glucose secondary transporters use the Na+ gradient (higher outside cells than inside) established by Na+/K+ ATPases to transport a molecule of glucose along with a sodium ion into cells.

What molecule provides energy for active transport?
Adenosine triphosphate (ATP) is the molecule that provides energy for active transport in cells. ATP is generated through cellular respiration and is used as a source of energy for various cellular activities, including active transport processes that move molecules against their concentration gradient.
Describe the two methods of active transport?
Active transport involves the movement of molecules against their concentration gradient, requiring energy input. Two methods of active transport include primary active transport, where energy from ATP is directly used to move molecules, and secondary active transport, where the movement of one molecule down its gradient provides energy to transport another molecule against its gradient.
What energy is used in active transport?
Active transport requires the input of energy in the form of ATP (adenosine triphosphate) to move molecules or ions against their concentration gradient across a cell membrane. This process is necessary for maintaining proper cellular function and regulating the internal environment of the cell.
What means of particle transport requires input of energy in a cell?
Active transport is a means of particle transport that requires the input of energy in a cell. This transport mechanism moves substances against their concentration gradient, from an area of lower concentration to an area of higher concentration, requiring energy to drive the process.
What are the two general types of transport used by cells to transport materials in and out of the cell?
The two general types of transport used by cells are passive transport, which does not require energy and includes processes like diffusion and osmosis, and active transport, which requires energy and involves processes like protein pumps and vesicle transport.
Is energy used in active transport?
ATP is often used as the source of energy during 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.
What molecule supplies the energy for active transport?
Adenosine triphosphate (ATP) is the molecule that supplies the energy for active transport in cells. ATP is produced during cellular respiration and carries energy that is used by transport proteins to move molecules against their concentration gradient.
Is energy used in secondary active transport?
Yes, any form of active transport uses energy.
What molecule provides energy for active transport?
Adenosine triphosphate (ATP) is the molecule that provides energy for active transport in cells. ATP is generated through cellular respiration and is used as a source of energy for various cellular activities, including active transport processes that move molecules against their concentration gradient.
Where is energy used in active transport?
in the cells
Energy used to fuel active transport?
ATP
What energy is used during active transport?
ATP
Is used during active transport but not passive transport?
ATP (adenosine triphosphate) is used during active transport but not passive transport. Active transport requires energy to move substances against their concentration gradient, while passive transport relies on diffusion to move substances down their concentration gradient without the need for energy.
What is the most direct source of energy for co-transport?
The most direct source of energy for co-transport is typically the movement of ions down their electrochemical gradient. This gradient is generated by active transport processes like ATP pumps. The energy stored in this gradient can be used to drive the co-transport of other molecules against their concentration gradient.
What cells use active transport?
Energy, versus passive in which energy is not used.
What perform active transport cells use?
Energy, versus passive in which energy is not used.
