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.
Is active transport ATP dependent?
Active transportation need energy.That energy is given by ATP.
What do most active transport use energy from breakdown for?
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.
active transport reguires?
Active transport requires some form of energy input, usually 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.
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.
Is ATP an active transport?
yes it is
Which type of membrane transport process uses ATP as a source of energy?
Active transport processes use ATP as a source of energy to move molecules against their concentration gradient across a cell membrane. This process requires specific transport proteins, such as ion pumps, to actively transport molecules across the membrane.
