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.
The electromagnet consists of two coils, each wound on a soft iron core fixed to the poles of a strong permanent horse-shoe magnet. The arc is produced by leading a current of about 5000 volts equatorially between the poles of an electromagnet; this produces what is practically a disk of flame, 62 ft.
