Factors Affecting Enzymes
The Role of Ezymes in Biological Reactions
The laws of thermodymatics apply to chemical reactions anywhere in the universe. ... Enzymes cannot make a reaction occur that would not proceed spontaneously without the enzyme. ... Enzymes do not alter the equilibrium point of reversible reaction. ... However, without enzymes, glucose oxidation occurs do slowly at physiological temperatures that the rate is essentially unmeasureable.
The increases in rate achieve by enzymes, depending on the enzyme and reaction, range from a minimum of about a million to as much as a trillion times faster than the uncatalyzed reactions at equivalent concentrations and temperatures. ...
Characteristics of Enzymes
Enzymes are protein molecules that are tailored to recognize and bind specific reactants and speed their conversion into products. ...
Table 1: Characteristics of enzymes proteins
1. Enzymes combine briefly with reactants during an enzyme-catalyzed reaction. ... Enzymes are released unchanged after catalyzing the conversion of reactants to Product
3. Enzymes are specific in their activity; each enzyme catalyzes the reaction of a single type of molecules or a group of closely related molecules. ... Enzymes are saturated by high substrate concentrations. ... Many enzymes contain nonproteins groups called cofactors, which contribute to their activity. ... Many enzymes are pH and temperature sensitive
The rate of combination and release, known as the turnover number, lies near 1000 per second for most enzymes.
