What happens when lactase is added to lactose?
When enzymes are boiled they become denatured, meaning they lose their function because they lose their shape. Any change in temperature or pH other than the one they are accustomed to will disturb an enzyme's shape; simply reverse their environment changes, and they'll go back to their correct function.
Can an enzyme continue to ract with other molecules once it has finished reacting with one?
Yes, proteic enzymes are not denatured by reacting with their substrates.
In a denatured enzyme what would happen to the enzyme?
they dont do anything because they are unable to bond with a substrate.
How does temperaure affect living things?
Living organisms run on biochemical reactions, and these reactions are affected by temperature. Any chemical compound is going to break down at a sufficiently high temperature, and any liquid (other than helium) is going to freeze solid at a sufficiently low temperature. Every organism has an certain temperature range in which it functions most successfully.
Why does increasing temperature stop an enzyme from working?
Although enzymes can become more active when the temperature increases, once it reaches beyond a certain threshold, enzymes are said to become "denatured". Once denatured, the enzymes become damaged and can no longer fit into each other in order for a reaction to occur.
Optimum temperature of polyphenoloxidase?
The optimum temperature for the enzyme polyphenol oxidase (PPO) is 40 degrees Celsius. This is the temperature at which the enzyme is most effective; like many other enzymes the rate of reaction will decrease with temperature, but if the temperature rises much above the optimum level, it will cause the enzymes to denature. Denatured enzymes will stay denatured even if the temperature decreases again. The optimum pH for polyphenol oxidase is 5.
What is effect of temperature on an enzyme?
Many of the enzymes in our bodies work best at body temperature. At significantly lower temperatures the substrate molecules do not have enough kinetic energy for the reaction to take place even in the presence of the enzyme. At body temperatures significantly higher than normal, the enzyme will not work well because the kinetic energy from the molecules in the solution containing the enzyme is so high, that the enzyme's shape is pulled apart to the point that the enzyme is not able to properly function.Indeed the enzyme's structure may be so disrupted or denatured that the enzyme molecule cannot return to its original shape. Indeed the danger of high fevers stems in large part from the potential damage to enzymes and other proteins from the high temperature. The optimum performance of most human enzymes is at about 37o celcius, or the temperature of the human body. Exposing enzymes to elevated temperatures can cause them to denature, which basically means they will no longer be functional. Enzymes are more active at a specific temperature. At higher temperatures they get denatured, so their structure breaks down. Same effect as pH. At lower temperatures they become inactive, in this case when they reach their optimum temperatures, they will become active again.temperature directly affects the rate of enzyme activity.On every 10 degree Centigrade rise in temperature,rate of enzyme activity doubles.but temperature affects up to its optimum range.For example:optimum temperature range of human is 37 degree centigrade.beyond this level of temperature,it can destroy the enzyme's structure and enzyme can be denatured due to fast vibration among its molecules which can lead to the bonds to break

How does an enzyme become denatured?
An enzyme becomes denatured when: A) the temperature exceeds the optimum temperature for that enzyme (ie the temperature that it works best at) B) the pH of the surrounding of the enzyme is too low or too high for the optimum pH for that enzyme. When enzymes are heated up too much they vibrate so vigorously that the bonds holding the protein structure in its specific shape becomes broken. The enzyme shape changes and the substrate no longer fits in to the active site. An enzyme which has become denatured is permanently inactive and will take no further part in reactions.

Yes, proteic enzymes are not denatured by reacting with their substrates.
Why would an enzyme produce more product at one temperature more so then another?
Enzymes do not 'produce' products. They increase the speed of the reactions they work on, for instance we react starch with water to produce maltose, and this is catalysed by amylase. Temperature affects the activity of the enzyme because of two factors:Thermal motion. As the temperature decreases, particles move more slowly and therefore collide less frequently, consequently the reactants and the enzyme encounter each other less often and the reaction is slowed.Denaturing. Above a certain temperature the chemical structure of the enzyme is destroyed and it can no longer work.Thus there is an optimum temperature for the action of the enzyme.

they dont do anything because they are unable to bond with a substrate.

How the surface temperature affects the year?
The time of year it happens to be affects the temperature not the other way round.

Why does the enzyme act as catalyst?
A) The enzyme does not actively take part in the reaction. It just indicates that the reaction is complete. B) Enzymes react with the substrate molecules to form products and become denatured in the process. C) Enzymes ensure that the reaction continues without inhibition even if conditions such as temperature and pH are changed. D) The products of the reaction are released from the active sites of the enzyme, allowing other substrate molecules to bind with the sites.
