Реферат: BIO Notes On Organic Chemistry Essay Research

· TYPES

Extracellular enzymes are produced and leave cell to work outside

· Intracellular enzymes work inside cell

ENZYME CONTROLLED REACTION

· Maltose (substrate) àmaltase (enzyme) à glucose (product)

PROPERTIES

· Always proteins

· Specific

· Reusable

· Destroyed by heat over 45 Celsius

· Sensitive to pH

HOW DO THEY WORK?

· Enzyme molecule has active site

· Substrate fits into active site

· Reaction takes place

· Products leave site.

HELPING HINDERING

· Anything which helps substrate reach enzyme speeds up reaction

· Poisons stop temporarily/ permanently the active site

ENZYME USE

· Biological washing powders

· Tenderising meats, skinning fish, removing hairs

· Softening vegetables, removing seed coats

· Syrups, fruit-juices, chocolates
