Enzymes Which of the common features are shared between serine and aspartate proteases? Both use a base to activate the nucleophile Both show specificity for certain amino acid sequences Both require water to complete the catalytic cycle All of these Both use a base to activate the nucleophile Both show specificity for certain amino acid sequences Both require water to complete the catalytic cycle All of these ANSWER DOWNLOAD EXAMIANS APP
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 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 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 function as a proton shuttle neutralize the charge on the other's side chain keep the specificity pocket open clamp the substrate into the active site function as a proton shuttle neutralize the charge on the other's side chain keep the specificity pocket open ANSWER DOWNLOAD EXAMIANS APP
