Question contain STATEMENT-1 (Assertion) and STATEMENT-2 (Reason).Question has 4 choices (a), (b), (c) and (d) out of which ONLY ONE is correct.
Statement 1 : Enzymes lower the activation energy.
Statement 2 : A substrate molecule can be acted upon by a particular enzyme
Activation energy is an external supply of energy which is needed for the initiation of the chemical reaction.Activation energy required for such a large number of reactions cannot be provided by living systems. Enzyme slower the activation energy required for a reaction.Enzymes are generally specific for their substrates.
Pentoses and hexoses are the most common
Pentoses and hexoses are the example of monosaccharides
Sucrose is made up of glucose and fructose, which are reducing sugars; but sucrose is a non-reducing sugar, because the linkage involves :
As the 1st carbon of glucose and 2nd carbon of fructoseare combined, the anomeric carbon atoms of both are not available for the reduction property.
