ATP (adenosine triphosphate) is a high-energy molecule that serves as the primary energy currency of cells, providing the energy necessary for various biological processes. Active transport is a cellular process that uses energy, often derived from ATP, to move substances across cell membranes against their concentration gradient. This mechanism is crucial for maintaining concentration differences of ions and other molecules inside and outside the cell, enabling essential functions like nutrient uptake and ion regulation.
What else can I help you with?
Do all types of active transport use ATP energy?
Not all types of active transport directly use ATP as an energy source. Primary active transport relies on ATP to move substances against their concentration gradient, such as the sodium-potassium pump. In contrast, secondary active transport utilizes the energy generated from the movement of one molecule down its gradient to drive the transport of another molecule against its gradient, often indirectly linked to ATP usage. Therefore, while ATP is crucial in some active transport processes, it is not a requirement for all.
What are two major means of active membrane transport?
Two major means of active membrane transport are primary active transport, which directly uses energy in the form of ATP to transport molecules against their concentration gradient, and secondary active transport, which uses the energy stored in the electrochemical gradient of one molecule to drive the transport of another molecule against its gradient.
What type of organic molecule is needed for active transport?
ATP (adenosine triphosphate) is the organic molecule needed for active transport. It provides the energy required to pump molecules against their concentration gradient across a cell membrane.
How much ATP does this cost the cell if it uses transport proteins?
The cost of ATP for a cell using transport proteins depends on the type of transport mechanism employed. For active transport, which moves substances against their concentration gradient, the process typically requires the hydrolysis of one ATP molecule per transport cycle. In contrast, facilitated diffusion through transport proteins does not require ATP, as it occurs along the concentration gradient. Therefore, if active transport is utilized, it costs the cell one ATP per transport event.
Is active transport ATP dependent?
Active transportation need energy.That energy is given by ATP.
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.
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.

What supplies the energy for active transport?
Mitochondria are what supplies energy to cells for active transport. ATP is the molecule that does this. Also known as adenosine triphosphate.
Which type of transport is used to move a molecule for a region of low concentration to a region of high concentration?
Active transport is used to move a molecule from a region of low concentration to a region of high concentration. This process requires energy input in the form of ATP to pump the molecule against its concentration gradient.
What are two major means of active membrane transport?
Two major means of active membrane transport are primary active transport, which directly uses energy in the form of ATP to transport molecules against their concentration gradient, and secondary active transport, which uses the energy stored in the electrochemical gradient of one molecule to drive the transport of another molecule against its gradient.
Is ATP an active or passive molecule in cellular processes?
ATP is an active molecule in cellular processes.
What type of molecule movement involves the use of ATP?
Active transport. This is movement of molecules against the concentration gradient.
What role does active transport play in diffusion?
active transport is kind of like diffusion, but unlike diffusion, it requires ATP(energy) and the molecule moves from low concentration to high concentration
The use of energy to move substances across a cell membrane describes?
Active transport, which requires energy in the form of ATP to move substances against their concentration gradient across a cell membrane. This process involves specific protein pumps that bind to the molecule being transported, consuming ATP to change conformation and move the molecule across the membrane.
