One purpose of feedback inhibition is to prevent too much of the product from being made. Feedback inhibition balances production of amino acids, the building blocks of proteins. For example, the enzyme threonine deaminase is inhibited by one of its products: the amino acid isoleucine.
A temporary magnet created when current flows through wire wrapped in coils around an iron bar. Heat Energy The movement of thermal energy from warmer to cooler objects.
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of insulated wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole in the center of the coil.
