Enzymes Enzyme-driven metabolic pathways can be made more efficient by concentrating enzymes within specific cellular compartments grouping enzymes into free-floating, multienzyme complexes All of these fixing enzymes into membranes so that they are adjacent to each other concentrating enzymes within specific cellular compartments grouping enzymes into free-floating, multienzyme complexes All of these fixing enzymes into membranes so that they are adjacent to each other 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 changing the three-dimensional shape of the molecule oxidizing the molecules by removing electrons changing the reaction from a biosynthetic to a catabolic pathway the input of a small amount of activation energy changing the three-dimensional shape of the molecule oxidizing the molecules by removing electrons changing the reaction from a biosynthetic to a catabolic pathway ANSWER DOWNLOAD EXAMIANS APP
