The enzyme has an optimal point of pH at which the enzyme works best. For example a catalase enzyme works best in a pH of 7. When the pH changes it denatures the enzyme causing it to not be able to react with the substrate.
A low temperature can slow down enzyme activity and high temperatures can denature an enzyme making it unusable. pH levels also affect enzyme activity. Every cell has an ideal temperature and pH
1) Change in membrane permeability and/or voltage 2) Enzyme activation/inactivation 3) Initiation of secretory activity 4) Synthesis of regulatory molecules such as enzymes
The enzyme with lowest pH optimum is pepsin. Pepsin works in the stomach in an acidic environment and aids in digestion.
Many things can denature proteins. Proteins have different optimal ranges in pH and temperature and outside of these optima then the enzyme will not work as well or at all. Also specific detergents will denature an enzyme depending on the enzyme.

Factors affecting enzyme activity1: Enzyme concentrationIf the quantity of enzyme is doubled, the enzymatic activity will also be doubled because more enzymes are now available to work. After a certain level of enzyme concentration, there will be no more increase in the enzymatic activity because all the substrate molecules are combined with an enzyme and the rate of reaction will stabilize.2: Substrate concentrationBy increasing substrate concentration, enzymatic activity increases. Increasing the substrate further without increasing the enzyme concentration will not affect the enzymatic activity because all the enzymes are occupied by a substrate molecule.3: pH valueSome enzymes require acidic surroundings, most require a more neutral condition for their activity. Change in the pH can change the enzyme's structure and enzyme become useless.4: TemperatureAn increase in temperature of 10 degree celsius doubles the enzymatic activity. Each enzyme has its own optimum temperature at which its enzymatic activity is maximum. Very high temperatures break the bonds that maintain shape of enzyme. If the enzyme denatures, the substrate can not fit in to the active sites and enzyme become useless.

There are four main factors that influence food choices. These factors include income, availability, cooking methods and facilities as well as cultural background.
yes it can. In about 3-4 years of you having your period I can regulate itself
The factors of 4 are 1, 2, and 4. The prime factors of 4 are 2 x 2.
There are two main types of feedback inhibition: competitive inhibition, where an inhibitor competes with the substrate for the active site of an enzyme; and non-competitive inhibition, where an inhibitor binds to a site on the enzyme other than the active site, altering the enzyme's shape and reducing its activity.
