Adobe PDF documents can be multi-page documents or single-page documents, and can include an array of graphics and text in an assortment of colors.
Which fact is most important in explaining how enzymes speed reactions? Very low potential energy tends to make molecules unstable. High-energy collisions are less common than low-energy collisions. It takes less energy to break a hydrogen bond than a covalent bond. Large molecules collide more energetically than small molecules. Every reaction step adds to the time required for the overall reaction. Study Enzyme Activity.
Enzymes accelerate, or catalyze, chemical reactions. The molecules at the beginning of the process are called substrates and the enzyme converts these into different molecules, called products. Almost all metabolic processes in the cell need enzymes in order to occur at rates fast enough to sustain life.ollowing Buchner's example, enzymes are usually named according to the reaction they carry out: the suffix-ase is combined with the name of the substrate (e.g., lactase is the enzyme that cleaves lactose) or to the type of reaction (e.g., DNA polymerase forms DNA polymers).
