Section: Unit Five: Enzymes | BAB 1206: Basic Biochemistry | kmtc

  • a)  Introduction

    Enzymes; - are specialized proteins that are involved in catalysis i.e. they spread up biological reaction. There are 2 types of enzymes depending on where they are produced. They include; intracellular enzymes which are used in the cell where they are produced. Extracellular enzymes are produced by other cells and are secreted to other parts of the body where they are utilized e.g. digestive enzyme.

    Zymogen – enzymes which are produced in their inactive forms and they have to be activated before they are able to function e.g.pepsinogen.

    Zymase – enzymes produced ready for action-Amylase.

    Substrate – substance upon which enzymes acts.

    Active site of an enzyme - a small region on the enzyme where a substrate binds for catalysis to take place.
