Enzyme Catalysis Lab Introduction: Enzymes ar very of the essence(p) in the functioning of cells and allow constant life to exist. Enzymes are proteins that movement as a catalyst which means that they continue answer rates. Substrates which are the substances that are being catalyzed, stick unneurotic to an enzyme at the active site, which resembles a bonding site in the midst of them both(prenominal). At this point, the enzyme speeds up the reaction that would occur slowly normally, and produces a harvest-home from the substrate. However, enzymes may sometimes fail to work properly for many another(prenominal) a(prenominal) reasons, and this dead enzyme is known to be denatured. One main promoter that denatures an enzyme is the salt immersion. Having too little of a salt preoccupation would not allow the enzyme to function, and in the same way an overburden of salt concentration would produce the same results. The pH stupefy in which enzymes are located is also another define factor of enzyme functionality. Certain enzymes are specific to pH levels at which they work best, and removing them from this environment may denature the enzyme. Much resembling pH levels, enzymes have an optimal temperature level, and again in a different temperature extreme, enzymes will denature.

However, other than only environmental factors, enzymes dismiss down also have their reactions affected by both activators, which affix reaction rates, and inhibitors, which slow or stop reactions. In an audition involving the unexpected lowering of pH in an enzymes environment, we spate think how the enzyme will become denatured because of this.
