Impeller vs. Inducer — What's the Difference?

An impeller or impellor is a rotor used to increase the pressure and flow of a fluid. It is the opposite of a turbine, which extracts energy from, and reduces the pressure of, a flowing fluid.

In molecular biology, an inducer is a molecule that regulates gene expression. An inducer functions in two ways; namely: By disabling repressors.

The rotating part of a centrifugal pump, compressor, or other machine designed to move a fluid by rotation.

One that induces, especially a substance that is capable of activating transcription from specific genes within a cell.

One that impels, as a rotating device used to force a fluid in a desired direction under pressure.

A part or structure in an embryo that influences the differentiation of another part.

A rotor or rotor blade.

One who induces.

Something which or someone who impels.

A molecule that starts gene expression.

A rotating component that accelerates fluid outward from a center of rotation, found in devices such as pumps, water jets, washing machines, and agitated tanks.

One who, or that which, induces or incites.

One who, or that which, impels.

A substance which, when it contacts a living cell, causes the activation of a gene; as, non-metabolizable inducers are useful for studying the kinetics of genetic control systems.

The blade of a rotor (as in the compressor of a jet engine)

An agent capable of activating specific genes

Someone who tries to persuade or induce or lead on
