Question

General principles of catalysis biology discussion

Answer 1

Answer:

Explanation:

Let us make an in-depth study of the enzymes. After reading this article you will learn about: 1. Meaning of Enzymes 2. Classification of Enzymes 3. Mechanism of Enzyme Action 4. Factors Affecting Enzyme Action 5. Enzyme Specificity 6. EnzymMeaning of Enzymes:

Enzymes are proteinaceous (and even nucleic acids) biocatalyst which alter (generally enhance) the rate of a reaction.

Free energy of activation and effect of catalysis:e Inhibition and 7. Diagnostic Importance of Enzymes.A chemical reaction like substrate to product, will take place when a certain number of substrate molecules at any instant, possess enough energy to attain an activated condition called the “transition state” in which the probability of making or breaking a chemical bond to form the product is very high. “Free energy of activation” is the amount of energy required to bring all the molecules in one gram mole of a substrate at a given temperature to the transition state.In presence of a catalyst, the substrate combines with it to produce a transient state having a lower energy of activation than that of the substrate alone. This accelerates the reaction. Once the product is formed, the enzyme (catalyst) is free to combine with another molecule of the substrate and repeat the process. Though there is a change in the free energy of activation in presence of an enzyme, the overall free energy change of the reaction remains the same wheClassification of enzymes are based upon:

(1) The reaction catalysed,

(2) The presence or absence at a given time,

(3) The regulation of action,

(4) The place of action and

(5) Their clinical importance.

1. Classification Based upon the Reaction Catalysed:

Enzymes are broadly divided into six groups based on the type of reaction catalysed.

They are:ther the reaction is catalysed by an enzyme or not.
