Why do cells need to use active transport?

Cells use active transport to move substances against their concentration gradient or across a membrane with the help of energy from ATP. This process is necessary for the cell to maintain proper internal conditions, such as ion balance and nutrient uptake, which are essential for its survival and functioning.


The energy required for the mechanism of active transport comes from?

The product of ATP decomposition.


Why do cells need to use transport?

This energy comes from the molecule ATP,which stores energy in a form that cells can use


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.


Energy expended by the cell in order for active transport to occur usually comes from a substance known?

The energy for active transport usually comes from the hydrolysis of ATP (adenosine triphosphate), which releases energy that the cell uses to move molecules against their concentration gradient.


Which type of transport require energy?

Active transport requires energy in the form of ATP


What source of energy is used in active transport?

Active transport uses energy in the form of adenosine triphosphate (ATP) to pump molecules against their concentration gradient across a cell membrane. ATP provides the necessary energy for the carrier proteins involved in active transport to move molecules from an area of low concentration to an area of high concentration.


Why does an organism have to provide energy for active transport?

The ATP hos to be provided because Active transport works against diffusion. its like the difference between a ball rolling down a hill (Passive Transport) and then having to push it up the hill (Active transport).


Does active transport move from higher to lower concentration?

Active Transport- When molecules move from an area of lower concentration to an area of higher concentrationPassive Transport- When molecules move from an area of higher concentration ot an area of higher concentration (also called diffusion)


Describe the process of active transport?

Active transport is when a protein moves a certain material across the membrane from a region of lower concentration to a region of higher concentration. This means the substance is absorbed against the concentration gradient and energy is needed for this active transport to work. The energy is usually comes from adenosine triphosphate or ATP, every cell supplies its own ATP by cell respiration. Globular proteins or pump proteins or transporter proteins in membranes carry out the active transport, the membrane must contain a lot of these proteins so that the cell can control the contents of its cytoplasm precisely. An example of active transport is in human nerve cells where potassium ions are pumped in and sodium ions are constantly transported out of the cell by active transport into the external fluid bathing the cell to build up a store of potential energy or an electrical impulse that is used to transmit a nerve impulse.


How do animals transport materials?

Energy comes from fatty acids which form from excess glucose( sugar) and lipids( fats). When energy is needed these fatty acids cross into the mitochondria and are broken down into acetyl choline- which is the energy block. Animals, therefore, transport energy in fat cells.


Is a carrier protein an active transport or a passive transport?

They are used in both, in passive the molecules move in , then change the shape then leave and the entering and leaving are both by diffusion. in active transport molecules move in by diffusion, change the shape of the carrier protein, then because theyre moving into the cell where the molecule is in higher concentration energy is required to push the molecules out of the carrier proteins, this energy comes from ATP which is supplied to the carrier proteins.
