Statements : Enzymes are protenisns and enrzyme catalyused reactions re called biolgical catalysis .
Explanations : The activity of enzyme as catalyst is increased in presence of vitamins .

Assertion: Enzymes are proteins and enzyme catalysed reactions are called biological catalysis. Reason: The activity of enzyme catalysis increase in presence of vitamins.

The enzyme activity is increased in the presence of certain substances, known as

Which of the following set is having correct statements for enzyme catalyst? 1. Each enzyme is specific for a given reaction 2. the enzyme activity is maximum at optimum pH 3. The enzymatic activity is increased in presence of certain substances called co - enzymes 4. The favourable temperature range of enzyme activity is between 50-60""^(@)C

What are enzyme catalysts? Give two examples of enzyme catalysis reactions.

In the presence of an enzyme, the activation energy of a reaction

The activity of enzyme is increased in the presence of certain substances known as co-enzymes or acticators.

Statements : In the presence of promter, the activity of the catalyst is enhanced . . Expabnations : The promter increases the surface area of the catlyst nad thus enhancing the number of active centres .

How the presence of an enzyme affects the activation energy of a reaction?
