Inactive vs. Sluggish — What's the Difference?

Inactive is a TRPV channel in invertebrates. Inactive mutant flies show locomotor and hearing deficits.

Slow-moving or inactive

Not engaging in or involving any or much physical activity

Displaying little movement or activity; slow; inactive

Not active or tending to be active

Lacking alertness, vigor, or energy; inert or indolent.

Not functioning or operating; out of use

Slow to perform or respond to stimulation.

Not being in continuous use or operation

Habitually idle and lazy; slothful; dull; inactive

Retired from duty or service

Slow; having little motion.

(Chemistry) Not readily participating in chemical reactions; inert.

Having no power to move oneself or itself; inert.

(Medicine) Marked by the absence or lessening of disease activity.

Characteristic of a sluggard; dull; stupid; tame; simple.

(Physics) Showing no optical activity in polarized light.

Exhibiting economic decline, inactivity, slow or subnormal growth.

Not active, temporarily or permanently.

Habitually idle and lazy; slothful; dull; inactive; as, a sluggish man.

Not engaging in physical activity.

Slow; having little motion; as, a sluggish stream.

Not functioning or operating; broken down

Having no power to move one's self or itself; inert.

Retired from duty or service.

Characteristic of a sluggard; dull; stupid; tame; simple.

(chemistry) Relatively inert.

With little movement; very slow;

(physics) Showing no optical activity in polarized light.

(of business) not active or brisk;

A person who does not take action.

Slow and apathetic;

Not active; having no power to move; that does not or can not produce results; inert; as, matter is, of itself, inactive.

Not disposed to action or effort; not diligent or industrious; not busy; idle; as, an inactive officer.

Not exhibiting any action or activity on polarized light; optically inactive; optically neutral; - said of isomeric forms of certain substances, in distinction from other forms which are optically active; as, racemic acid is an inactive tartaric acid.

Lacking biological or biochemical activity; not causing a specific biological or biochemical effect; - said of substances such as enzymes which have lost their catalytic power, or of small molecules which are tested for some type of biological activity and found to lack that activity; as, after boiling for ten minutes, the enzyme was totally inactive; the methyl analog was inactive as an antibiotic.

Not participating in a chemical reaction;

Not progressing or increasing; or progressing slowly

Not active or exerting influence

Of e.g. volcanos; temporarily inactive;

Lacking in energy or will;

Lacking activity; lying idle or unused;
