Adenosine Triphosphate Flashcards
Energy from glucose is released from
catabolism and captured in the bonds of ATP
* ATP is an energy transferring molecule in cells
and provides energy immediately usable by all
body cells
* An enzyme transfers the phosphate group from
ATP to another molecule (phosphorylation), the
molecule then become more energetic and
able to perform cellular work
* Cells are protected from excessive energy
release and energy is conserved
Adenosine Triphosphate
ATP phosphorylates transport proteins, activating them to transport solutes (ions, for example) across cell membranes.
Transport work
ATP phosphorylates contractile proteins in muscle cells so the cells can contract (shorten).
Mechanical work
ATP phosphorylates key reactants, providing energy to drive energy-absorbing chemical reactions.
