Enzymes Before they can react, many molecules need to be destabilized. This state is typically achieved through oxidizing the molecules by removing electrons changing the three-dimensional shape of the molecule changing the reaction from a biosynthetic to a catabolic pathway the input of a small amount of activation energy oxidizing the molecules by removing electrons changing the three-dimensional shape of the molecule changing the reaction from a biosynthetic to a catabolic pathway the input of a small amount of activation energy ANSWER DOWNLOAD EXAMIANS APP
Enzymes The cleavage specificity of trypsin and chymotrypsin depend in part on the proximity of Ser 195 to the active site or specificity pocket presence of a low-barrier hydrogen bond in the active site or specificity pocket size, shape, and charge of the active site or specificity pocket absence of water in the active site proximity of Ser 195 to the active site or specificity pocket presence of a low-barrier hydrogen bond in the active site or specificity pocket size, shape, and charge of the active site or specificity pocket absence of water in the active site ANSWER DOWNLOAD EXAMIANS APP
Enzymes The proteolysis rate enhancement by chymotrypsin (~1010 folds) corresponds to a reduction in activation energy of about 88 kJ/mol 40 kJ/mol 49 kJ/mol 58 kJ/mol 88 kJ/mol 40 kJ/mol 49 kJ/mol 58 kJ/mol ANSWER DOWNLOAD EXAMIANS APP
Enzymes The role of Asp 102 and His 57 during trypsin catalysis is to clamp the substrate into the active site neutralize the charge on the other's side chain function as a proton shuttle keep the specificity pocket open clamp the substrate into the active site neutralize the charge on the other's side chain function as a proton shuttle keep the specificity pocket open ANSWER DOWNLOAD EXAMIANS APP
