31 Μαρ 2024 · The activity of an enzyme is sensitive to temperature and pH, as discussed in Chapter 6. Variation in temperature and pH affect the structure of enzymes, which in turn affects their ability to bind substrates and catalyze reactions.
This section will explore the effect of temperature, pH, and enzyme concentration on the rate of a reaction.
There are two ways to discuss the thermodynamics of enzyme-catalysed reactions: (1) with chemical reactions written in terms of species (like ATP4-, HATP3-, and H2ATP2-) using the Gibbs energy G, enthalpy H, and entropy S. (2) with biochemical reactions written in terms of reactants (sums of species like ATP) at a specified pH and using the appa...
Introduction. The rate of an enzyme-controlled reaction is influenced by different factors including temperature, pH, enzyme concentration and substrate concentration. The effect of each of these factors can be determined by changing one variable only, and observing its effect on the reaction rate. In this practical, we will determine the ...
Simple Enzyme Kinetics. Basics. Enzyme kinetics studies the reaction rates of enzyme-catalyzed. reactions and how the rates are affected by changes in experimental conditions.
Provided that the substrate concentration is high and that temperature and pH are kept constant, the rate of reaction is proportional to the enzyme concentration. (See graph)
Investigate the effect of temperature on the rate of an enzyme-catalysed reaction, to include Q10. The rate of reaction of an enzyme-controlled reaction is influenced by different factors: the temperature, pH, concentration of the substrate, and the concentration of the enzyme.
