Enzyme Regulation and Reaction Speed

Here is a small map over the regulation of reaction speed within the body. There are four main types of modifiers.

Allosteric modifiers, for instance is the hemoglobin molecule influenced by binding oxygen molecules. The more oxygen molecules that bind to it, the higher the affinity for oxygen gets.

Covalent bindings, switches many enzymes on or off. The most common molecule involved is phosphate. Glycogen Synthase is shut off by being phosphorylated.

Co-Enzymes, are needed in many reactions. NADH is needed when alcohol dehydrogenase breaks down ethanol.

Enzyme Concentration is also a major factor when it comes to speed of reaction in many cases.
