Enzymes The cleavage specificity of trypsin and chymotrypsin depend in part on the absence of water in the active site proximity of Ser 195 to the active site or specificity pocket size, shape, and charge of the active site or specificity pocket presence of a low-barrier hydrogen bond in the active site or specificity pocket absence of water in the active site proximity of Ser 195 to the active site or specificity pocket size, shape, and charge of the active site or specificity pocket presence of a low-barrier hydrogen bond in the active site or specificity pocket 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 Which of the following is false statement with regard to comparison between Serine and HIV proteases?
