Three things that can alter the rate of an enzyme are; temperature, pH and substrate concentration.
Enzymes will have an optimal temperature and pH, at which they will have the greatest rate. Below or above these optimum conditions, the rate will be slower.
The concentration of maltose itself does not alter the rate of hydrolysis, as hydrolysis primarily depends on the presence of enzymes, such as maltase, or acidic conditions. Once the concentration is sufficient to saturate the enzyme or reactants, further increases in maltose concentration will not significantly affect the rate of hydrolysis. Other factors like temperature, pH, and enzyme concentration are more influential in altering the hydrolysis rate.
Enzyme concentration has no effect on the rate of an enzyme-catalyzed reaction after reaching a saturation point where all enzyme active sites are occupied. At this point, adding more enzyme will not increase the reaction rate further.
The rate of an enzyme-catalyzed reaction is often referred to as the enzyme's catalytic activity or turnover rate. It is a measure of how quickly the enzyme can convert substrate molecules into products.
TemperatureAs you increase the temperature of the system in which the enzyme is involved in, the rate of catalysis of the enzyme increases. However, one must make take note that the optimum temperature of the enzyme must not be surpassed because very high temperatures could change the structure of the protein-based enzyme, rendering the enzyme ineffective.Surface Area of the substrateIf you increase the surface area of the substrate, the enzyme will bind to more sites on the substrate and the rate of the reaction will therefore be faster.pHDifferent enzymes work in different environments. One of the factors that determine the state of the environment in which the enzyme operates is its pH. There are enzymes that exhibit optimum rate of catalysis of reactions at in an acidic environment while there are some that exhibit their optimum rate at a basic environment, while yet others only operate in relatively neutral environments.
Enzymes follow a specific procedure called "lock and key" model, where they bind to substrates to catalyze reactions. Factors that affect enzyme activity include temperature, pH, substrate concentration, and the presence of inhibitors or activators. These factors can alter the enzyme's structure, affecting its ability to bind to substrates and catalyze reactions effectively.

Factors that affect the rate of enzyme activity include temperature, pH, substrate concentration, and enzyme concentration. Temperature and pH can alter the shape of the enzyme, affecting its ability to bind to the substrate. Changes in substrate and enzyme concentration can affect the frequency of enzyme-substrate collisions, which impacts the rate of reaction.

Enzyme concentration has no effect on the rate of an enzyme-catalyzed reaction after reaching a saturation point where all enzyme active sites are occupied. At this point, adding more enzyme will not increase the reaction rate further.
The enzyme activity curve shows that as enzyme concentration increases, the reaction rate also increases. However, there is a point where adding more enzyme does not further increase the reaction rate, indicating that there is a limit to the effect of enzyme concentration on reaction rate.
The pulse rate and the heart beat of a human being is measured to alter his breathing rate.

A change in the rate of enzyme action in aquatic invertebrates would most likely result from a change in temperature or pH levels in their environment. Enzymes are sensitive to these factors, as variations can alter their structure and function, affecting metabolic processes. Additionally, changes in oxygen availability or substrate concentration could also influence enzyme activity.
