The correct option is (a) True
The explanation is: It would be useful if enzyme catalyzed reactions where performed in organic solvents, other than water because of the following reasons:
• Water is not the ideal medium for the majority of organic reactions.
• Many reactants such as molecular oxygen, steroids and lipids are more soluble in organic solvents than in water.
• For accomplishing reactions with reactants quite labile in an aqueous environment, non-aqueous media may be used which allows a much increased volumetric activity to be achieved.
• Microbial contamination is a lesser of a problem in organic solvents. As a result of this, microbial proteases are absent which leads to an apparent stabilization in the biocatalyst.
