Ph level and rate of reaction
Webb25 jan. 2024 · The rate of chemical reaction refers to how quickly the products are generated from the reactants. It provides some insight into how quickly a reply can be … WebbEvery enzyme has an optimum pH range, in which it can perform. For example : Pepsin has an optimum of pH 2.5 and a working range of between pH 1-4. Catalase has an optimum pH of 9 and a working range of between pH 7-11. Most other enzymes function within a working pH range of about pH 5-9 with neutral pH 7 being the optimum.

Webbför 2 dagar sedan · the rate of reaction is lowest, because the smallest amount of product has been formed. The Eadie-Hofstee plotrearranges the Michaelis-Menten equation as: v = Vmax - Km x v / [S] plotting v against v / [S] gives a straight line: y intercept = Vmax gradient = -Km x intercept = Vmax / Km This plot overcomes the problem
WebbV_ {max} V max is the Y-value (initial rate of reaction value) at which the graph above plateaus. The substrate concentration that gives you a rate that is halfway to V_ {max} V max is called the K_m K m, and is a useful measure of how quickly reaction rate increases with substrate concentration. K_m K m is also a measure of an enzyme's ... fit test for symptomatic patientsWebb14 sep. 2024 · pH is biologically important because it affects the structure and activity of macromolecules. pH is important in homeostatic processes.
