Enzymes Before they can react, many molecules need to be destabilized. This state is typically achieved through changing the reaction from a biosynthetic to a catabolic pathway changing the three-dimensional shape of the molecule the input of a small amount of activation energy oxidizing the molecules by removing electrons changing the reaction from a biosynthetic to a catabolic pathway changing the three-dimensional shape of the molecule the input of a small amount of activation energy oxidizing the molecules by removing electrons ANSWER DOWNLOAD EXAMIANS APP

Enzymes The cleavage specificity of trypsin and chymotrypsin depend in part on the absence of water in the active site presence of a low-barrier hydrogen bond in the active site or specificity pocket proximity of Ser 195 to the active site or specificity pocket size, shape, and charge of the active site or specificity pocket absence of water in the active site presence of a low-barrier hydrogen bond in the active site or specificity pocket proximity of Ser 195 to the active site or specificity pocket size, shape, and charge of the active site or specificity pocket ANSWER DOWNLOAD EXAMIANS APP
