  • Learning Objectives

    • To examine the function and properties of enzymes in living cells
    • To distinguish between substrate, enzyme, and product in a reaction
    • To collect and analyze data on tissue-specific catalase activity
    • To collect and analyze data on the effect of temperature on catalase action

    Thumbnail: Enzyme changes shape by induced fit upon substrate binding to form enzyme-substrate complex. Hexokinase has a large induced fit motion that closes over the substrates adenosine triphosphate and xylose. Binding sites in blue, substrates in black and Mg2+ cofactor in yellow.
