5. A physical analogy for chemical reactions Evaluate whather the folowing statemerts about enzyme catalyaed reactions are true or false Substrates are consumed and cannot participate in multiple rounds of the sama chemical reaction Enzymes can tun an endergonic reaction into an exergonic ona. Enzymes lower the actvation energy of a reaction. A sngle enzyma can bind a diverse ranga of substrates False The tollowing ilustration depicts mountain lake has gravitational potantiali energy. It wants to fnow downstream, but a high rocky barrier prevents b from doing so. Because the water is in motion, waves do hit the barier. As a result, a faw spleshes occasionaly make it over the barriar and flow downhil, but this occurs raresy an analogy for an uncatalyzed chemical reaction. In this analogy, water in a An Analogy for an Uncatalyzed Chemical Reaction of a chemical reaction The water in the high mountain lake is analogous to the To achiave a downill-fHowing stream of water, a change must bs mads.

Explanation / Answer

Substrates are consumed...True - the substrate goes on to give the product which would in most cases not be able to go back to the substrate's side via the same enzyme.
Enzymes can turn...False - the overall energy equation cannot change, only the difference for the intermediate.
Enzymes lower...True - hence the entire purpose of enzymes being called catalysts.
A single enzyme can...True - the enzyme is specific to a particular docking unit that it interacts with via bonds

The water in high mountain is analogous to the reactants.

Scenario paralleling the effect of adding a catalyst = Scenario A - lowering of barrier (intermediate) is what enzymes do.
Scenario paralleling the effect of adding extra reactant = Scenario D - addition of more water (reactants) is a way of forcing the reaction to occur and reach equilibrium by forming the products.
