Choose the answer that places the following steps involved in enzymatic catalysis of biological reactions into the logical sequence of events. 1. Enzyme free to repeat process 2. Enzyme-substrate complex forms 3. Chemical reaction 4. Product detachment 5. Substrate binding at the active site 6. Temporary reversible change in enzyme shape

The correct sequence of events in enzymatic catalysis is 5; 2; 6; 3; 4; 1.

Explanation:

Enzymatic catalysis or enzyme catalyzis refers to the process of increasing the rate of a reaction through the use of a biological molecule called an "enzyme". As with other catalysts, the enzyme is not consumed or changed by the reaction when used as a substrate but is recycled. Therefore, one enzyme can perform catalyzis several times. As mentioned, enzymes are a distinct group of catalysts capable of accelerating biochemical reactions without participating in the reaction. These enzymes are proteins that bind the substrates and reactants in an area of the molecule called the active site. As binding takes place, conformational alterations in the enzymes take place which result in the lowering of the activation energy required for the reaction to take place. Enzymes can catalyze reactions through a number of procedures, which include bond strain, proximity and orientation, proton donors and acceptors, electrostatic catalysis and covalent catalysis. This diversity makes enzymes very effective. And the specific of enzyme catalysis a explained in steps 1-6, in the order listed above.
