People Window Help ouse.com/mod/quiz/attempt.php?attempt-264419 The high energy unstable structure with characteristics of both the reactant and product is called? Select one a. the activation barrier b. the intermediate state C. the turnover state d. the transition state ° Which statement is correct? Select one: a. Some enzymes contain metal ions b. The typical biochemical reaction occurs more than one million times faster in the presence of an enzyme when compare( to the reaction without the enzyme O c. The catalytic function of enzymes is dependent on their three- dimensional structures O O d. All statements provided are correct What is a coenzyme?Explanation / Answer
In a reaction the unstable structure with the characteristics of both reactant and produt is transition state.
Transition state is very unstable and it has high energy.
Ex: SN2 reaction
OH- + CH3- X -----> [HO ----- CH3--------X] -------> CH3OH + X-
The compound in brackets is the transtion state
--------------------
a) yes, enzymes contains metals
ex: carbonic anhydrase enzme contains Zn metal
b) Yes, in the presenc of enzyme biochemical reaaction occur million times faster than reaction without enzyme.
c) yes, enzyme catalytic function depends on its three dimensional strutcure
d) all are correct.
