Welcome to Dr. Abbas Biology, In this channel you will learn deep concept all about biology. This channel will be totally based on conceptual lectures. • CHARACTERISTICS OF ENZYMES • Enzymes, the biochemical catalysts possess the following important characteristics. • 1. All enzymes are globular proteins. • 2. They increase the rate of reaction without themselves being used up. • 3. Their presence does not affect the nature or properties of end products. • 4. Small amounts of an enzyme can accelerate chemical reactions. • 5. They are very specific in their action; a single enzyme catalyzes only a single chemical reaction or a group of related reactions. • 6. They are sensitive to even a minor change in pH, temperature and substrate concentration. • 7. Some enzymes require a co-factor for their proper functioning. • 8. They lower the activation energy of the reactions. • Some enzymes are potentially damaging if they are manufactured in their active form. For example, pepsin is a powerful protein - digesting enzyme and is quite capable of destroying cell’s internal structure and thus is produced in inactive pepsinogen form by the cell. It is converted in its active form only in the digestive tract where it is required to be active. • #mdcatbiologylectures #neet2024 #biology #science #enzyme #characteristics of enzyme
