In an Organic Chemistry Lab, Chemical Reactions Are Mainly Carried

In an organic chemistry lab, chemical reactions are mainly carried out in organic solvents such as dichloromethane or hexane.Just down the hall in a biochemistry lab, chemical reactions are mainly carried out in aqueous buffers in which water is the solvent.If biochemical reactions involve organic compounds from biological sources, why aren't biochemical reactions carried out in organic solvents?

A) Organic solvents are more hazardous to use than water-based solvents.
B) Organic solvents require special disposal not required for water-based solvents.
C) Biochemical reactions can be slowed for easier study in aqueous solvents.
D) Biochemical reactions normally take place in a water-based solvent.
E) Biochemical reactions do not follow the same principles of chemistry that organic reactions follow.
