Enzymes Before they can react, many molecules need to be destabilized. This state is typically achieved through the input of a small amount of activation energy changing the reaction from a biosynthetic to a catabolic pathway changing the three-dimensional shape of the molecule oxidizing the molecules by removing electrons the input of a small amount of activation energy changing the reaction from a biosynthetic to a catabolic pathway changing the three-dimensional shape of the molecule oxidizing the molecules by removing electrons ANSWER DOWNLOAD EXAMIANS APP
Enzymes The role of Asp 102 and His 57 during trypsin catalysis is to neutralize the charge on the other's side chain keep the specificity pocket open function as a proton shuttle clamp the substrate into the active site neutralize the charge on the other's side chain keep the specificity pocket open function as a proton shuttle clamp the substrate into the active site ANSWER DOWNLOAD EXAMIANS APP
