Introduction Enzymes are catalytic proteins. The purpose of a catalyst is to speed up metabolic reactions by lowering the free energy of activation or activation energy. Activation energy is known as the amount of energy needed to push the reactants over an energy barrier‚ so that the downhill part of the reaction can begin (Campbell 151). In an enzyme catalyzed reaction‚ the enzyme binds to its substrate‚ which is the reactant an enzyme acts on. In the reactions‚ the enzymes are very specific

Abscitrim is highly concentrated form that that is potent and highly effective. What it does: - induces the closure in stomata to prevent transpiration and water loss - prevents fruit ripening - promotes seed dormancy by stopping cell growth and seed germination -stops synthesis of Kinetin nucleotide -Kinetin: cytokinin
