Enzyme activity is temperature dependent, increasing with rising temperature, reaching a maximum activity (known as optimum temperature), before it starts to decrease (Fig. 34.2B). The optimum temperature is different for each enzyme. Nevertheless, enzymes are proteins, and temperature excess (>60°...
An enzyme exhibits maximum activity over the narrow pH range in which a molecule exists in its properly charged form. The median value of this pH range is called theoptimum pHof the enzyme (part (b) ofFigure 18.14 “Temperature and pH versus Concentration”). With the notable exception of ...

This lesson addresses how temperature influences enzyme function, and provides a concrete example from a lab setting. The key terminology will include the words enzyme, catalase, denaturing, and reaction rate. Enzymes & Catalase Meet Mr. Corsini. He's a science teacher and one of the highlights...
The synthesis of cis-vaccenic acid is a critical metabolic function in response to decreasing environmental temperature. This process is regulated by the activity of KAS II. Abbreviations: KAS I, β-ketoacyl-ACP synthase I; KAS II, β-ketoacyl-ACP synthase II; KAS III, β-ketoacyl-ACP ...
temperature has on the rate ofenzymeactivity. The way we figured this out was by taking four different temperatures and testing the different absorbance levels they produced every 20 seconds for two minutes straight using a spectrophotometer. The important part of this experiment was the temperature...
