Graph of enzyme activity against temperature
Web1. [1 mark] The graph shows enzyme activity plotted against temperature. What is the reason for the drop in enzyme activity above 40 ∘ C? A. A decrease in the enzyme concentration B. Reaction is saturated because active sites are occupied C. Insufficient activation energy for the reaction to proceed D. Changes to the conformation of the enzyme http://brilliantbiologystudent.weebly.com/effect-of-temperature.html

Web4. pH – the rate of reaction of enzymes varies with pH, due to changes in the shape of the active site. An enzyme would have the highest rate of reaction at its optimum pH. A buffer might be used to maintain pH at a suitable level. Temperature – the rate of reaction of enzymes varies with temperature. As temperature http://brilliantbiologystudent.weebly.com/effect-of-temperature.html

Rate of Reaction/kPa min-1 against Temperature/°C WebAs temperature increases so do the rate of enzyme reactions. A ten degree centigrade rise in temperature will increase the activity of most enzymes by 50% to 100%. Variations in reaction temperature as small as 1 or 2 degrees may …
WebBiology questions and answers. Question 5 (1 point) The graph below shows enzyme activity plotted against temperature. What is happening at point ? Top The reaction is … WebBecause enzymes guide and regulate the metabolism of a cell, they tend to be carefully controlled. In this article, we’ll take a look at factors that can affect or control enzyme activity. These include pH and temperature (discussed in the active site article), as well as: Regulatory molecules.
Weban enzyme works as a catalyst. A graph of enzyme activity plotted against temperature is shown below. The enzyme in the graph above works most efficiently as a catalyst at 40 °C. This is the optimum temperature for this enzyme. Above 40 °C the enzyme begins to work less efficiently as a catalyst because the shape of the enzyme molecule starts ...
