Which property of enzymes is being investigated
Answers
Enzymes increase the rate of reaction and remain unaffected by the reaction which they catalyse. Specificity of enzyme: Enzymes are highly specific in nature, i.e., a particular enzyme can catalyse a particular reaction. For example, Enzyme sucrase can catalyse only hydrolysis of sucrose.
Answer:
PROPERTIES OF ENZYMES
(i) Protein nature: Enzymes are generally proteins. They may have additional inorganic or
organic substances for their activity.
(ii) Chemical reaction: Enzymes do not start a chemical reaction but increase the rate of reaction.
They do not change the equilibrium but bring about equilibrium very soon.
(iii) Efficiency: The number of substrate molecules changed per minute by a molecule or enzyme is
called turn over number. The higher the turn-over number, the more efficient an enzyme is.
(iv) Unchanged form: enzymes are in no way transformed or used up in the chemical reaction but
come out unchanged at the end of reaction.
(v) Enzyme specificity: Enzymes are highly specific in their action. For example, enzyme maltase
acts on sugar maltose but not lactose or sucrose.
