Can the product of a reaction that is part of a sequence act as an inhibitor for another reaction in the sequence? Explain. 200010 STA + ulo

According to the following graph, the activity of the enzyme decreases more sharply at high temperature than at low temperature. What are the reasons for this observation? Enzyme activity Optimum temperature Temperature, °C I. As temperature is increased, the substrate binding slowly becomes poorer. II. As temperature is decreased, the enzyme moves more slowly and so reacts more slowly. III. At higher temperatures, the enzyme is denatured and stops working entirely. IV. Temperature has no effect on enzyme activity. ○ I only O IV only I and III O II and III

How does changing the concentration of enzyme at a fixed concentration of substrate affect the rate of decomposition of H2O2?

An enzyme has an optimal pH of 7.1 and an optimal temperature at 37° C. Which statement describes a reaction catalyzed by this particular enzyme at a constant temperature of 20° C? the reaction will slow down and then increase as the temperature increases O there is no effect O the reaction will be slower than if it ran at 37° C O the enzyme will provide an alternate active site so the reaction can proceed the enzyme will be denatured
