If an enzyme is a protein how might you change the specificity of such an enzyme?
What an enzyme does is based on its shape, therefore you would have to change it on a molecular level in order to alter its job. ...
What might happen to the functioning of an enzyme if the gene that codes for it was altered by a mutation?
If a gene that codes for a particular enzyme is altered by a mutation, the enzyme will not function properly. The mutated gene will not be recognized by the receptor site of the enzyme, and its proper function will not activated. ...

What effect might a change in pH have on enzyme activity?
Any change in pH will cause a decrease in enzyme activity. This decrease in the rate of reaction is because it will change the shape of the enzyme molecules. ...
Asked in Science
If the shape of a protein is changed what else is changed?
If shape of a protein is changed its function is altered. This might change or stop a particular biochemical pathway in which that enzyme was critical. Specific 3D shape of each protein is very essential for its function. Change in shape of proteins is caused by a mutation in the DNA. ...

How do changes in pH and temperature affect the native confirmation of an enzyme?
Enzymes are quite easy to break.So if the pH is too acidic,then the enzyme might break.Therefore if the temperature is too high,the enzyme will also break. ...
Asked in Biochemistry
How might very low pH affect an enzyme's hydrogen bonds?
A very low pH can break the hydrogen bonds in an enzyme which causes the shape of the enzyme to change shape making the enzyme unable to do it's job. This is called "denaturation" However some enzymes such as pepsin only work in a low pH (pepsin works best in a pH of about 3) so it does depend on the enzyme. ...
How at the molecular level pH might affect enzyme activity?
Enzymes work best at a certain PH. If the PH is higher or lower than ideal, it will show down the rate at which the enzyme works. ...
Asked in Photosynthesis
How might environmental conditions affect enzyme activity?
Things like pH and temperature affect it. Environmental conditions change the shape of enzymes irreversibly so that it won't work anymore. Like a lock and key, if someone melted your key then you would need a new one. ;) ...
Will enzyme activity increase with an increase in temperature?
It might. Enzymes have optimal pH and temperature ranges. Change the pH or temperature and the shape of the enzyme will change. When this happens, the enzyme will work differently. If you increase the temperature from too cold to just right, enzymatic activity will increase. If you increase the temperature from just right to too hot, it will decrease. ...
How might the lack of water in a cell affect the cell's enzymes?
It affects it by if the cell doesn't have water then the enzyme can't speed up a chemical reaction. ...

What must be held constantly when testing the effects of enzymes concentration on enzymes activity?
any factors that might affect enzyme efficinientcy, such as temperature and ph ...

What things might slow down or speed up and enzyme reaction?
The temperature in addition to the pH sacle of something in particular in the environment would affect the rate of speed of an enzyme and would slow down the reaction if it is too high. ...
Asked in Biology
How might a choice in pH affect the function of an enzyme such as hexolkinase?
Simply put, enzymes are proteins and proteins can denature (break) under the right conditions. These conditions would include temperature and pH (however these are not the only factors) and so the changing of pH could definitely affect hexolkinase (or did you mean hexokinase? which would make more sense). ...
Asked in Biology
What are several different situation in which an enzyme might lose its specific shape?
An enzyme can lose its shape (tertiary structure) through many ways. Some of these include: pH change, increased heat, or change in ionic strength of the solution (increasing or decreasing salt levels). ...
Asked in Evolution
What is affect evolution?
The term coevolution (affect) is used to describe cases where two (or more) species reciprocally affect each other's evolution. So for example, an evolutionary change in the morphology of a plant, might affect the morphology of an herbivore that eats the plant, which in turn might affect the evolution of the plant, which might affect the evolution of the herbivore and so on. ...
Asked in Microbiology, Biology
How might a change in pH affect the function of an enzyme such as hexokinase?
Many enzymes are affected by changes in temperature. Cells can regulate the activities of enzymes in many ways. Most cells contain proteins that help turn key enzymes "on" and "off" at critical stages in the life of the cell. Enzymes play essential roles in regulating chemical pathways, making materials that cells need, releasing energy, and transferring information ...
