The activity of an enzyme is affected by temperature, pH and the concentration of the substrate.
Enzyme become denatured.
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.

It will affect the shape and lead to reduced activity.
Enzymes have an individual optimum pH, such as pepsin has a very low optimum pH
pH and Temperature both impact the enzyme's function.

No. They function best at the pH corresponding to their usual/intended environment. For example, pepsin, present in the stomach, which is highly acidic, functions best at acidic pH, while trypsin, secreted into the duodenum together with basic bicarbonate, functions best at moderately basic pH. This is true also within subcellular compartments: the optimal pH of lysosomal enzymes is acidic, matching the acidic proteolytic environment inside the lysosome. That said, most enzymes present in the cytosol (~neutral) and blood (~neutral) function best around neutral pH.

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).
They only function when the acidity or alkalinity of their environment is at a certain level.
