Enzymes are biocatalysts. They catalyse biochemical reaction. In general they reduce activation energy of reactions. Many physico-chemical processes are enzyme mediated. Some examples of enzyme mediated reactions are given below. Tick the wrong entry

A

Dissolving `CO_2` in water

B

Untwining the two strands of DNA

C

Hydrolysis of sucrose

D

Formation of peptide bond

Text Solution

Verified by Experts

The correct Answer is:
d
Formation of peptide bond needs the enzyme peptidyl transferase. In fact NCERT itself mentions ''There is no uncatalysed metabolic conversion in living systems, every chemical reaction in them is a catalysed reaction."

Classify the enzymes based on the type of reaction they catalyse.

Classffy enzymes into five types based on the type of reactions they catalyse.

[A] : The energy derived from enzyme-sub-strate interaction , is called energy of formation . [R] : Free energy is the major source of energy used by enzymes to lower the activation energies of reactions .

In general it is observed that the rate of a chemical reaction doubles with every 10 degree rise in temperature. If the generalization holds good for the reaction in the temperature range 295 K to 305 K, what would be the value of activation energy for this reaction ? [R = 8.314 mol^(-1)JK^(-1)]
