What's the difference between activity and inertness?

Activity


Definition:

  • (20) Together these results suggest that IVC may operate as a selective activator of calpain both in the cytosol and at the membrane level; in the latter case in synergism with the activation induced by association of the proteinase to the cell membrane.

Inertness


Definition:

  • (n.) Want of activity or exertion; habitual indisposition to action or motion; sluggishness; apathy; insensibility.
  • (n.) Absence of the power of self-motion; inertia.

Example Sentences:
