Any kind of active transport.
Sodium ions moving out of the cell
Active transport... Not anything passive though.
ATP is the energy currency of life that provide energy to the biological reactions. Kinases that phosphorylate their substrates require ATP. Membrane channel proteins that conduct active transport needs ATP. These proteins utilize the energy found in ATP, by breaking them in to ADP plus inorganic phosphate.
active transport
ATP supplies energy that fuels cell activities.
The special kind of molecules that store energy for later use are adenosine triphosphate (ATP) molecules. These molecules store up the energy they get from the mitochondria (kitchen of the cell) in the cell. In the human body, unused energy is stored in the from of glycogen and in plants it is stored as starch.
An example of how cells use energy is when they make use of an energy-dependent transport in the cell membrane. Some types of non-passive transport require ATP for it to work, hence using "energy"
Energy released from ATP
Breaking the bonds in ATP releases the energy in the bonds. Making ATP would "trap" the energy. The difference in the ion gradient across a membrane happens during cellular respiration. The enzyme ATP synthase makes ATP. It allows protons to pass through the membrane using the kinetic energy to add P to ADP making ATP. ATP production occurs in chloroplasts and mitochondria.
energy molecules that breaks down into energy when needed by the body
A concentration gradient is a representatinve of energy storage. ATP the energy currency of the cell will require this conc. gradient for its formation. HIgher the conc. gradient the higher will be the stored energy and high the no of ATP can be formed.
