Question

ruin the following table to describe the effect incubating an organism above or below its optimal growth temperature has on molecules required for survival? Structure Below the optimal Temperature Above the optimal temperature Enzymes Membranes 5. Design an experiment which would allow you to determine whether an organism isolated at room temperature (around 20 °C) was a psychrotroph or a mesophile. Make sure your answer predicts where you would expect to see growth for each type of organism, and how this can be used to classify the organism.

Answer 1

4)

Structure	Below optimum temperature	Above optimum temperature
Enzymes	The molecules will have less kinetic energy and therefore less enzymatic activity	Causes denaturation of enzymes and therefore decreases enzyme activity
Membranes	decreases membrane permeability	causes denaturation of membrane
