Final answer:
The factor that does not influence enzyme action is relative humidity.
Step-by-step explanation:
The factor that does not influence the action of enzymes is relative humidity. Enzymes are highly sensitive to changes in temperature, reactant concentration, and pH. Temperature affects the rate of enzyme activity, with most enzymes having an optimum temperature for activity. The amount of reactant determines the rate of enzyme-substrate reactions, as more reactant molecules provide more opportunities for enzymatic reactions to occur. pH also plays a crucial role in enzyme activity, with specific enzymes functioning optimally in different pH ranges.
