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 else can I help you with?
Active transport involves what?
Active Transport requires first of all Energy which is obtained from respiration and secondly a selectively permeable membrane through which movement of materials can take place.
What is the energy source of most cellular activity?
Adenosine triphosphate (ATP) is the main energy source for most cellular activities. It is produced during cellular respiration through the breakdown of glucose and other nutrients in the presence of oxygen. ATP stores and releases energy for various cellular processes, such as muscle contraction, protein synthesis, and active transport.
What nucleotide that drives most energy reqy?
Adenosine triphosphate (ATP) is the nucleotide that drives most energy-requiring processes in cells. It stores and releases energy as needed for various cellular activities, such as muscle contraction, enzyme reactions, and active transport across cell membranes.
Which type of respiration produces the most energy for the cell?
Aerobic respiration produces the most energy for the cell because it involves the complete breakdown of glucose in the presence of oxygen, leading to the production of a large amount of ATP through the electron transport chain.
List the key distinguishing feature of active transport proteins?
i dont not know so someone answer it soon please:(
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.
Active transport involves what?
Active Transport requires first of all Energy which is obtained from respiration and secondly a selectively permeable membrane through which movement of materials can take place.
How are active transport and passive transport different from each other?
Active transport requires energy input to move substances across a membrane against their concentration gradient, while passive transport does not require energy as it moves substances along their concentration gradient. Active transport is selective and requires specific transport proteins, while passive transport occurs through simple diffusion or facilitated diffusion.
The process of active transport requires the most direct use of?
The process of active transport requires the direct use of cellular energy, usually in the form of adenosine triphosphate (ATP). This energy is needed to move molecules across a cell membrane against their concentration gradient.
What is the key feature of active transport?
The key feature of active transport proteins is that they can use chemical energy to move a substance against its concentration gradient. Most use energy from a molecule called ATP, either direvtly or indirectly.
Is active transport low concentration to high concentration?
Yes. Active transport requires energy; it is transport from an area of low concentration to an area of high concentration. Passive transport doesn't require energy; it is transport from an area of high concentration to an area of low concentration.
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.
How are most nutrients absorbed through the mucosa of the intestinal villa?
Active transport driven directly or indirectly by metabolic energy ;)

ATP stores and releases energy for various cellular processes, such as muscle contraction, protein synthesis, and active transport.
What happens to most of energy from breakdown of food?
We concentrate on glucose breakdown, since it dominates energy production in most animal cells.
What does active transport mean in medical terms?
active transportation is the one that requires energy. passive transportation doesn't require energy and particles move because of differences of concentration - it's diffusion and osmosis. most common energy source in cells is ATP, also ADP and AMP. active transportation also requires special proteins in cell membrane. those proteins use energy to transport iones and molecules from one side of membrane to another.
What happens to most of the from the breakdown of food?
We concentrate on glucose breakdown, since it dominates energy production in most animal cells.
