At high temperatures, the rate of enzyme action decreases because the increased heat?
increases the concentration of the enzyme
neutralizes the acids and bases in the system
alters the active site of the enzyme
Enzymes influence chemical reactions in living systems by?
affecting the rate at which reactions occur
providing the substrate required for the reaction to occur
combining with excess hydrogen to form gaseous wastes
The "lock and key hypothesis" attempts to explain the mechanism of enzyme specificity
At about 0 C., most enzymes are?
The optimum temperature for the action of this enzyme is approximately
