Adenosine Triphosphate Flashcards

1
Q

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
