Answer to Question #5706 in Biochemistry for SHAGUFTA PARVEEN
EXPLAIN HOW ENZYMES LOWER THE ACTIVATION ENERGY OF A REACTION
The activation energy of a reaction is lowed with 2 ways: 1) Entropic catalysis: an enzyme binds 2 substrates in the special orientation against an active center of the enzyme. 2) Enthalpy catalysis: Before the covalent bonds rebuilding of the substrates it appears an intermediate-compound, to which the enzymes is more related. It provides lower activation energy.
