How do enzymes affect standard free energy?
Standard free energy doesn't change with an enzyme. Rather, the enzyme acts to redirect that reaction in a particular way, lowering the required energy for the reaction to occur but not changing the energy amount involved.
How does a non-competitive activator affect enzyme activity?
Well, unlike competitive inhibitors the non-competitive inhibitors will not compete the active site of the enzyme with substrate . Instead, it will combine with the enzyme somewhere except the ative site and alter the whole shape of the enzymes therefore the active site of substrate and enzyme are not the same and therefore no enzyme-substrate complex can be formed and the enzymatic effect can't be restored becausr the enzymes are now denatured
How do you prepare 1 percent solution of hydrogen peroxide?
Fractional crystalization of Hydrogen Peroxide would involve lowering the temperature of the solution to just above the melting point. This will depend on the concentration and it is NOT linear. For instance, a 3% solution as is found in most drugstores will freeze at about -2C, 30% at about -25C, 35% at -33C, 50% at -52C, 70% at -40C and finally 90% at about -11C.
Why would a washing powder of high pH or low pH be difficult to handle?
actors such as temperature and pH can affect an enzyme's rate of reaction because enzymes are sensitive to pH and heat. Most enzymes can only function in a particular temperature or pH range, and as the enzyme works out of its normal temperature and pH range, it will denature (change in shape so that the active site no longer fits with the substrate and the enzyme can't function).
Would form would form a non-electrolyte solution in water?
Some examples of a non-electrolyte solution in water would be a solution of sugar, or a solution of urea. These do no ionize in solution and so are non-electrolytes.
What is the effect that lowering the temperature would have on the rate of enzyme activity explain?
It would lower the speed of the reaction but will do no harm to the enzyme.
How do enzymes affect standard free energy?
Standard free energy doesn't change with an enzyme. Rather, the enzyme acts to redirect that reaction in a particular way, lowering the required energy for the reaction to occur but not changing the energy amount involved.
Enzymes speed up chemical reactions by?
by lowering the activation energy of reactions
What is bourgeoisie's solution to over production?
Lowering prices so that they can compete with their competitors would be my guess
What would be unlikely to contribute to the substrate specificity of an enzyme?
The allosteric site is distinct from the active site, and does not affect the substrate specificity of the enzyme
Some surgical procedures involve lowering a patients body temperature durng periods when blood flow must be restricted. what effect might this have on enzyme-controlled cellular metabolism?
Lowering the body temperature would lower the temperature in the cells, this causes the substrates to slow down, in a sense be less hyperactive, thus lowering the chance that the substrate will come in contact with its given enzyme. This will lower the overall Cellular Metabolism
In what way would a defective enzyme affect an organism if it was involved in metabolic reactions that produce ATP?
Non-working enzyme → no ATP → no energy → death.
What affect would temperature and pH have on the Catalans enzyme?
Just like always, deviating from the desired normal functioning for the enzyme, whether it be in temperature or pH, would result in the enzyme denaturing and therefore being unable to for enzyme substrate complexes, therefore reducing the overall reaction rate.
If a base is added gradually to a solution with a pH of 6 containing enzyme C and its substrate the rate of action of enzyme C would most likely?
(2) increase, then decrease
What effect does substrate and enzyme joining have on chemical bonding?
enzyme catalyze the biochemical reactions by lowering their activation energy. An enzyme which take part in such reaction wont be lost or gained any chemical structure and it would be the same after the reaction.
Will lowering the pH of lactose affect the enzyme?
Yes, it would effect the enzyme as i would become acidic. If it becomes too acidic then the shape of the active site will change and the substrate will no longer fit and therefore no reaction can take place. A low pH will denature the enzyme ( cause the protein structure to change shape)
