When the organism is resting and energy is not immediately needed, the reverse reaction takes place and the phosphate group is reattached to the molecule using energy obtained from food or sunlight.

ATP (adenosine triphosphate) is the energy-carrying molecule used in cells because it can release energy very quickly. Energy is released from ATP when the end phosphate is removed. Once ATP has ...

A diverse array of biophysical and biochemical approaches have lent strong support for the swinging cross-bridge model ... ATP to the rearward head to release it from the actin filament. Single ...

Exactly how much ATP is produced per oxygen molecule consumed ... they are a tractable experimental model. But he came at the question from the standpoint of bacterial physiology — how do ...

If oxygen is available to the cell then the pyruvate molecules can be further broken down in stage two to release more energy and produce a greater quantity of ATP. A pyruvate molecule enters the ...

Kinetic measurements of kinesin-1's front and rear heads reveal how different neck linker orientation regulate their activity, enabling the motor protein to move in a coordinated manner along ...

Similarly, in the cell model of the person with mutations ... the building blocks of adenosine triphosphate, or ATP, an energy molecule made by the mitochondria that fuels cell metabolism.
