What must be held constant when testing the effect enzyme concentration on enzyme activity?
temperature,pH and substrate concentration
What effect does cooking have on enzyme activity?
You mean heating the enzymes? heating to a certain degree increases their rate of catalytic activity, until about 30-40 degrees Celsius. However if you continue heating, the enzyme's basic structure will be deformed (it changes shape), and since structure is essential to function, the enzymes activity will be reduced. that happens around 60-70 degrees Celsius, but it is different in various organisms.
In order to to become a functioning liveries enzyme the string must?
I am not sure
How does heating a enzyme affect its function?
For an enzyme to work it must bind to a specific substrate molecule, using a part of the enzyme molecule called the active site. To do this, the enzyme's active site and the substrate must have matching (complementary) shapes. The shape of an enzyme molecule depends on the exact way in which the molecule folds up. When enzymes are heated the weak bonds which hold the molecules in their precise shape are broken, and the enzyme molecule "unwinds" into a random shape. It can no longer bind with its substrate so it no longer has any activity. This "unwinding" of a protein molecule is called denaturation.
What happens to the rate of enzyme reaction when you increase the enzyme concentration?
As the enzyme concentration increases, the rate of reaction will increase because there are many more enzymes present to aid break down the substrate. However, a point will be reached when no matter how much enzyme is present, the reaction will not occur any quicker. This is equilibrium. This happens because all the substrate is being broken down by the exact same amount of enzyme, so enzymes will be present which have no substrate to break down.
What can you do to regain the activity of the enzyme?
The enzyme is inactive at this point. New enzyme must be added to regain enzyme activity
In cell isolation why must cold buffer and centrifugation be carried in cold temperatures?
TO STOP ENZYME ACTIVITY
Which subatomic particles have mass and re included in the calculation of the atomic mass number?
These particles are protons and neutrons; but to be correct the mass of electrons must be added.
What conclusion can you draw from enzyme activity throughout the body?
Life needs very rapid help in working. Also that there must be many complicated reactions going on.
Which of the following is not one of the three basic steps involved in enzyme activity?
"Because their catalytic role renders most enzymes ineffective after their initial activity, a cell must produce large amounts of each enzyme in order to perform effectively." this is incorrect because 99+% of enymes are used until the cells dies because they are costly (in energy terms) to make.
What must be held constant when testing the effect enzyme concentration on enzyme activity?
temperature,pH and substrate concentration
How do you prepare enzyme?
To prepare an enzyme, you must start with material with a high concentration of the enzyme, and then purify it many times. Be sure to avoid excessive heat.
What happens to the enzyme after the substrate is changed?
enzyme works as a catalyst before and after the reaction it is preserved
What kind of energy must be provided for an enzyme to function?
Activation
How does temperature and pH affect amylase activity and why?
Anylase works best in a slightly basic pH so a very acidic pH will denaturate the enzyme making it unable to do it's job.Effects of pHEnzymes are affected by changes in pH. The most favorable pH value - the point where the enzyme is most active - is known as the optimum pH.Extremely high or low pH values generally result in complete loss of activity for most enzymes. pH is also a factor in the stability of enzymes. As with activity, for each enzyme there is also a region of pH optimal stability.In addition to temperature and pH there are other factors, such as ionic strength, which can affect the enzymatic reaction. Each of these physical and chemical parameters must be considered and optimized in order for an enzymatic reaction to be accurate and reproducible.Hope this helps ;)
