What is the independent variable between temperature and enzyme activity?
To find out how enzyme concentration affects the activity of the enzyme you must:vary the concentration of the enzyme, by preparing different concentrations (keeping the volume of solution the same)keep the temperature, substrate concentration and pH constantmeasure the activity of the enzyme at each concentrationHow the enzyme activity is measured will depend on the specific enzyme involved.You need to have plenty of substrate (excess substrate) so it doesn't run out during the experiment.In this type of experiment, the enzyme activity is the dependent variable, the temperature, pH and substrate concentration are control variables and the enzyme concentration is the independent variable.
What are the four factors that effect enzyme activity?
The four factors that affect enzyme activity are temperature, pH, substrate concentration, and the presence of inhibitors or activators. Temperature and pH can alter the enzyme's shape, while substrate concentration determines the rate of reaction. Inhibitors and activators can either decrease or increase enzyme activity, respectively.
What are 3 things that can alter enzyme activity?
1. Temperature. 2. P.H level. 3. Enzyme concentration
How does initial concentration of substrate effect enzyme activity?
At low concentration of substrate , rate of enzyme action is directly proportional to conc. of substrate .
Would you expect similar results if the substreate concentration were varied in the same manner as the enzyme concentration?
Yes, varying substrate concentration in a similar manner to enzyme concentration would likely yield similar results in terms of reaction rates, especially if the enzyme follows Michaelis-Menten kinetics. Initially, increasing substrate concentration typically increases the reaction rate until a saturation point is reached, where all enzyme active sites are occupied. Beyond this saturation point, further increases in substrate concentration would not significantly enhance the reaction rate, similar to the behavior observed with varying enzyme concentration.
Can an enzyme be hydrolyzed by another enzyme?
Yes
At which enzyme concentration was starch hydrolysed the fastest?
The rate of starch hydrolysis is typically fastest at an optimal enzyme concentration, which varies depending on the specific enzyme and conditions. Generally, increasing enzyme concentration increases the rate of starch hydrolysis until a saturation point is reached, where all substrate molecules are engaged with enzymes. Beyond this saturation point, additional enzyme does not significantly enhance the reaction rate. Therefore, the fastest hydrolysis occurs at the optimal enzyme concentration just before saturation.
What is the usual fate of dietary lecithin?
hydrolyzed by the intestinal enzyme lecithinase
How does increasing enzyme concentration affect the rate of enzyme action when the enzyme concentration remains constant?
It doesn't
What factors affect the rate of enzyme activity?
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.
What is hydrolyzed beef plasma?
Hydrolyzed beef plasma is an ingredient in bodybuilding concentrate. The beef blood is introduced to an enzyme for partial digestion breaking into easy to digest amino acid chains.
How does increasing substrate concentration affect the rate of enzyme action when the enzyme concentration remains constant?
It doesn't
What are some factors that affect enzyme speed?
Substance concentration, enzyme concentration, temperature and PH level
How does increasing enzyme concentration affect the rate of enzyme action when substrate concentration remains constant?
It doesn't
Calculation fraction of enzyme bound to substrate?
The fraction of enzyme bound to substrate can be calculated using the Michaelis-Menten equation: [ES] / [E]t = [S] / (Km + [S]), where [ES] is the concentration of enzyme-substrate complex, [E]t is the total enzyme concentration, [S] is the substrate concentration, and Km is the Michaelis constant. This equation gives the ratio of the concentration of enzyme bound to substrate to the total enzyme concentration at a given substrate concentration.

What does the enzyme activity curve reveal about the relationship between enzyme concentration and reaction rate?
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.
