BIOL 220 Study Guide - Midterm Guide: Adenosine Triphosphate, Atp Hydrolysis, Ribose
Document Summary
P-o bonds are high energy, and if those bonds were to be broken they would go into a lower energy state. In doing so, they would release more energy. Hydrolysis of adenosine triphosphate- one phosphate will come off. The electrons in this bond go into a lower energy state and release energy. Atp hydrolysis mechanism (atp to adp) free energy. Although this reaction is spontaneous, you don"t have it happening all the time because you need atpase) Oh: the lone pair of electrons on water (or other molecule) does a nucleophilic attack on the phosphorous in the phosphate group, oxygen takes back electrons in bond, giving it a negative charge. For electrons on oxygen with negative charges to get close to the negative charges on atp, you need activation energy. Atpase surrounds atp with positive molecules so it can keep the electrons on atp busy while the water does to nucleophilic attack.
