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

Enzymes Enzyme-driven metabolic pathways can be made more efficient by grouping enzymes into free-floating, multienzyme complexes concentrating enzymes within specific cellular compartments fixing enzymes into membranes so that they are adjacent to each other All of these grouping enzymes into free-floating, multienzyme complexes concentrating enzymes within specific cellular compartments fixing enzymes into membranes so that they are adjacent to each other All of these ANSWER DOWNLOAD EXAMIANS APP
Enzymes The cleavage specificity of trypsin and chymotrypsin depend in part on the absence of water in the active site size, shape, and charge of the active site or specificity pocket 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 absence of water in the active site size, shape, and charge of the active site or specificity pocket 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 ANSWER DOWNLOAD EXAMIANS APP
