What are the 4 factors that affect enzyme activity?
The factors that affect enzyme activity are: temperature, concentration of substrate (the amount of the substance the enzyme is going to work on) and the pH of the medium it works ...

Describe factors that may influence enzyme activity?
There are 4 factors. Temperature, pH, enzyme concentration, and substrate concentration. Temperature increases enzyme activity till an optimum temperature which after that drastically reduces its activity due to the enzyme protein denaturing. All enzymes function at a specific pH range, (change in pH results in change in structure due to the ionic bonds present between amino acids) high enzyme concentration results in higher effective collision between enzyme and substrate. therefore activity increases. High substrate concentration results in higher activity as the rate of effective collision increases,...

What are some factors that may influence enzymes activity?
Factors affecting enzyme activity 1: Enzyme concentration 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...

What are the four main properties of enzymes?
An enzyme capable of hydrolyzing 4-methylumbelliferyl phenylphosphonate to 4-methylumbelliferone and phenylphosphonic acid has been detected in human serum. It has a Km value of 1.72 x 10(-4) mol/L, has an optimum pH of 8.8-9.1 in Tris buffer, and shows maximum activity at 60 degrees C (30 min). The enzymic activity can be inhibited by Na3PO4, EDTA, and cysteine. We saw no effect of CuSO4, adenosine, thymidine, NaN3, diethyl p-nitrophenyl phosphate, p-chloromercuribenzoate, isopropyl fluorophosphate, or eserine on the enzymic activity. The enzyme cannot hydrolyze substrates...
