  • Scientists study dissimilation to understand how cells obtain energy from nutrients.

Examples

  • During intense exercise, dissimilation provides the necessary energy for muscle contraction.

  • Many metabolic diseases interfere with normal dissimilation processes in the body.

  • The process of dissimilation is crucial for cellular respiration.

  • During dissimilation, energy is often released as a byproduct.

Morphology

dissimilation = dissimilar (opaque) = dis + simil + ation

Although formed from dis- + simil + -ation, the biological sense 'breakdown of complex substances' is not derivable from 'dissimilar' and represents a specialized semantic development.

Etymology

Dissimilation comes from the parts dis- meaning 'not' and similis meaning 'like', so it literally means 'not alike'. In biology, dissimilation is the breaking of complex substances into simpler parts to release energy, so the root shows it is about making things less alike by breaking them down.
