A change in pH or and change in temperature will change the shape of the enzyme because its proteins are denatured. Therefore, the enzyme can no longer perform its desired functions because its specific shape has been altered.
Almost all enzymes are proteins, and only function in a specific range of temperature and pH. This is due to the fact the enzyme can only work if it stays in a particular shape, imagine it as being a lock, ready to accept a specific key, representing the chemical substrate it works on. Excess temperature or change in pH can alter the shape of the enzyme - 'denature' it, meaning the substrate no longer 'fits', the enzyme can no longer function as normal.
All enzymes are very reactive to pH change. Every enzyme has an optimum acting range above or below which it can't act. For example the optimum range for pepsin is 2-3 and it won't act below or above it.
It is so because pH changes cause ionization in enzyme structure which results in it denaturing.
Enzymes are most reactively at a optimum pH and temperature. At a optimum pH enzymes are most reactively because a enzyme of acidic nature is more reactively at acidic pH, while it is not good reactive at basic pH.
acids have a ph greater than 7
All enxymes work at an optimum pH. Changes in pH levels could change the rate at which the enzymes work by denaturing them.
Most enzymes only work in a certain pH range; pH is not dependent on the presence of enzymes, however.
Most enzymes work best at a certain pH, however there are some enzymes that can operate over a broad pH range.
The activity of the enzymes depends on the specific pH needed.
Enzymes have an individual optimum pH, such as pepsin has a very low optimum pH
temperture.
enzymes
Enzymes are sensitive to changes in pH and only work with a relatively small pH range. Since vinegar is an acid, the pH of the solution containing the enzymes is changes when vinegar is added.
It disrupts an enzymes shape and structure.
That depends on the physical conditions. High temperatures, some substances or changes in pH cause enzymes to be permanently denatured. Very low temperatures and the presence of some inhibitors cause enzymes to be temporarily unable to catalyse reactions.
if u mean 'what are the factors that denature enzymes?' the answer is:--------- changes in pH and an increase in temperature
All enxymes work at an optimum pH. Changes in pH levels could change the rate at which the enzymes work by denaturing them.
Enzymes operate best under a tight, optimal range of pH values. Extreme pH can seriously affect enzyme activity, so it is little wonder that big changes in pH can slow down enzyme activity. Extreme changes can often irreversibly inactivate and denature an enzyme.
Most enzymes only work in a certain pH range; pH is not dependent on the presence of enzymes, however.
Every enzymes has its own optimum pH and temperature, where it shows higher activity (pH:it is very specific; temperature:mostly not more than 30-37degree C). Above or below this situation the enzymes activity may differs exponentially due to the biochemical changes.
Temperature/pH/Substrate Concentrate and Inhibitors
The activity of an enzyme is affected by temperature, pH and the concentration of the substrate.
