IB Biology HL C1.1.13 Hl Cyclical and Linear Pathways in Metabolism Topic Practice

Question 1

[Maximum number: 1]

Laccase is an enzyme that has the ability to decompose synthetic dyes used in the production of clothing and thus could potentially help reduce synthetic dye pollution.

An experiment was performed in which laccase was immobilized in alginate beads to determine the effectiveness of laccase immobilization in decolorizing the dye crystal violet. The graph shows the effect of laccase concentration on relative decolorization activity of the immobilized laccase. Error bars represent ± SD.
