The prefix "macro" means large, so they are large molecules, composed of hundreds, thousands, or even more atoms. Most of these important for our biological functions are organic, meaning that they contain many carbons and hydrogens, and usually with oxygens as well.
The four main types of macromolecules present in all living things: proteins (composed of amino acids), carbohydrates, lipids (fats), and nucleic acids. They are all organic, thus contain carbon and hydrogen.

Which statement most accurately explains how allosteric regulation can change an enzyme's catalytic activity? View Available Hin
Digiron [165]

Answer:

In allosteric inhibition, a regulatory molecule binds to a location other than the active site, resulting in a change in enzyme shape that allows the active site to bind substrate.

Explanation:

Allosteric regulation of an enzyme can be positive or negative, but it always involves effector molecules that bind to non-active site of the enzyme and change its conformation. That site of binding is called allosteric or regulatory site. If the enzyme activity is enhanced effector molecule is called allosteric activator but if the activity is decreased effector molecules are allosteric inhibitors.
