What is the purpose of GUAIACOL?
Guaicol is used as a substrate for peroxidase activity, when we treat it with enzyme the activity of enzyme increases at a higher rate.
What is it about enzymes that determines which reaction they catalyse?
Enzymatic reactions depend on the concentration of the substrate. Once all active sites become filled, the output of product obviously depends on something else. This could be the pH of the solution, the temperature of the solution, or many other factors. Usually, higher temperature means high kinetic energy (motion) of molecules and faster reaction times. However, too hot of a temperature can denature the enzymes active site. Also, different enzymes work more or less efficiently in different pH levels. Also, the overall affinity for the substrate by the enzyme influences the rate. Inhibitors can also affect rates.
Why does stirring affect diffusion?
Stirring decreases the time it takes for a substrate to dissolve in a solvent. More of the substrate is exposed to the solvent, thus, allowing it to dissolve quicker. This is similar to why increasing surface area during a chemical reaction, increases the rate of the reaction.
What inhibitor binds into the active site of an enzyme not allowing the subrtate to bind?
This would be a competitive inhibitor. It can be a structural analog of the substrate. This type of inhibition can be out competed by adding more substrate. A competitive inhibitor increases the Km of the enzyme.
How the Vmax achieved in Michael's- Menten equation?
Vmax is the maximum possible rate that can be achieved by the addition of substrate. It levels off at v max because availability of substrate is no longer a limiting factor. Km is defined by 1/2 of Vmax. In reality Vmax levels off but then the curve goes down once substrate concentration increases viscosity.
The graph below shows how two different enzymes react with a substrate as the temperature increases. Based on the results what conclusion can be drawn about the action of the enzymes as the temperatur?
enzyme B stays effective at higher temperatures than enzymes A
How show two different enzymes react with a substrate as the temperature increases?
Enzyme A becomes less effective earlier than enzyme B.
What factors affect enzyme activity?
Temperature - too cold the enzyme will still work but slowly, too hot and the enzyme will become denatured . As temperature increases, the kinetic energy of the molecules increases so they move around more, meaning that there are more collisions between the enzymes and substrate molecules and therefore more reactions. pH - different types of enzymes work best in different pH environments. A change in pH interferes with the shape of the enzymes active site (where it bonds and reacts with substrate) and therefore does not fit the shape of the substrate as well so the enzyme is unable to work on the substrate. enzyme and substrate concentration - how many there is of each. Changing the concentrations of enzyme and substrate concentrations will affect the number of collisions between them and therefore the number of reactions. enzyme inhibitors - these are molecules which bind to enzymes, reducing their activity (many drugs are enzyme inhibitors). co-factors - these are chemical compounds which bind to enzymes and which are needed by the enzyme to work on substrate molecules. They are often called helper molecules.
Some factors that may influence enzyme activity?
A low temperature can slow down enzyme activity and high temperatures can denature an enzyme making it unusable. pH levels also affect enzyme activity. Every cell has an ideal temperature and pH
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 happens to an allosteric enzyme when the concentration of substrate around the?
B. it increases its processin capacity
How do you dry out clay substrate?
you leave it out in room temperature overnight
What effect enzymes activity?
Temperature, pH, substrate concentration
3 factors that influence enzyme activity?
The three main factors that affect enjyme activity are:- a)Temperature:Enzymes generally function properly at a narrow rangr of temperature and shows its highest activity t a particular temperature called its optimum temperature. b)pH:-as temperature pH also has a particular value ,in which the enzymes are most active,called the optimum temperature. c)Concentration of substrate;-with the increase in substrate concentration,the velocity of the enzymatic reaction also increases,till a maximum velocitywhich does not rise any further with the rise in substrate concentration.
What are two factors that influence enzyme activity?
Concentration of the enzyme or it's substrate and the temperature.
What happens to an allosteric enzyme when the concentration of substrate around the molecule increases?
THE ANSWER IS B (IT INCREASES IT'S PROCESSING CAPACITY) JUST DID THE TEST the answer is definitely B
How do enzymes affect reactions?
The initial velocity of a gradually increases during enzyme substrate reaction. The concentration of the substrate also increases with it.
