If 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 concentration
By 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 value
Some 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: Temperature
An 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.

What are some environmental enzyme factors?
Enzymes are catalysts that speed up chemical reactions. Some environmental factors that can affect enzyme activity are temperature and pH levels.
Substances that plug up an enzyme's active site are?
Blocking of enzyme activity depends on various factors such as concentration of substrates, pH, temperature, some durgs. As for example rifampicin durg blocks RNA polymerase II activity.
Some factors that may influence enzyme activity?
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
What are some factors that could impact the function of an enzyme?
This depends on the enzyme. Temperature, pH, and the presence of co-factors, or allosteric inhibitors.
What are molecules that take part in the enzyme activity but are not proteins?
Non-protein compounds called co-factors are required for some proteins in order to facilitate enzymatic activity. Common examples of co-factors are metal ions (Ca2+, Mg2+ etc.), organic co-factors such as heme (in hemoglobin), among others.
Some medicines work by blocking enzyme activity in pathogens These medicines are effective because they?
have a shape that fits into the enzyme
What are some enzyme co factors?
One is cofactor A.
What are some factors that affect enzyme speed?
Substance concentration, enzyme concentration, temperature and PH level
What are some of the factors that influence or control the mechanical and chemical weathering of rocks?
Temperature, rainfall, vegetation, animal activity, type of rock being weathered.
How do temperature pH and enzyme concentration each influence enzyme activity?
Hydrogen peroxide (H2O2) is a poisonous byproduct of metabolism that can damage cells if it is not removed. Catalase is an enzyme that speeds up the breakdown of hydrogen peroxide into water (H2O) and oxygen gas (O2).
What are some factors that can affect the shape of an enzyme?
Locamotion, cell movement, biosynthesis
What factors are there that influence HNS operations?
Some of the factors that influence the HNS operations are logistics, the personnel and dependability. Other factors are competition and the availability of the local resources.
