Why do enzymes show different rates of reaction or no reaction in different pH environments? Explain why enzyme activity varies with pH and how temperature can affect the rate of an enzyme reaction. Describe why you can not test the effects of two parameters (like p...
•Enzymes are catalytic proteins that accelerate the rate of chemical reactions by lowering the amount of energy needed to start the reaction. -when remove activation energy the reaction goes faster What do enzymes do? speed up chemical reactions by lowering the activation energy...

Enzymes serve to catalyze the rates of reactions by altering the minimum energy required for the reaction to proceed (activation energy). The enzyme does not have a thermodynamic effect on the reaction but promotes it as the lat...
speed up a specific chemical reaction without itself being destroyed or changed in any way. They are produced by the living organism and are usually present in only very small amounts in various cells. proteins catalysts that speed up the rate of a chemical reaction by lowering the activation ...
Berthellot (1862) derived second-order equations for the rates of ester formation and, shortly after, Harcourt observed that rates of reaction doubled for each 10 °C rise in temperature. Guldberg and Waage (1864-67) demonstrated that the equilibrium of the reaction was affected by the ...
assay. Reaction rates were determined by fitting progress curves using linear regression and are expressed as initial turnover rates (µM/s). Controls contained fecal extract that had been heat-killed at 95 °C for 5 min. Reported rates are the average of three biological replicates ±...
Why do enzymes show different rates of reaction or no reaction in different pH environments?Why are enzymes important? a. Because they allow reactions to occur at body temperature. b. Because they increase body temperature. c. Because they're proteins. d. Because they can evade the laws of ...
