The Ea (enzyme) is less than Ea (uncatalyzed). How does this change the spontaneity of the reaction?
Enzyme do not change the spontaneity of the reaction.
Enzyme change the activation energy which makes the reaction faster.
But Enzyme cant make a non spontaneous reaction occur.
Answer:
Enzyme do not change the spontaneity of the reaction.

Effect of a Catalyst on Reaction Rate: with a lower Ea than for the uncatalyzed reaction. This is shown as the blue path with Ea in the diagram below t a given temperature, a catalyst increases the rate of a reaction by providing a pathway E (RJ) products Reaction Coordinale Since the potential energy barrier is lower in the presence of a catalyst, a greater fraction of the molecules will have sufficient energy to react. Because the reactants and products...
Compared to the uncatalyzed reaction, which parameters change in the presence of an enzyme? All of the above change. O Keq
Uncatalyzed Catalyzed Enzyme-substrate Complex In the above reaction, the lower curve is an enzyme-catalyzed reaction where the activation energy is notably lower than the uncatalyzed reaction. Suppose the enzyme in the diagram was mutated in such a way that its affinity for the substrate increased 100 fold, thereby affecting the enzyme-substrate complex portion of the curve. Assume that there was no other effect. Would you expect the reaction rate catalyzed by the altered enzyme to be faster, slower, or equal...
How does a change in pH affect the structure of an enzyme? At what level might change occur (1,2,3,4) and WHY?
How does PH influence enzyme activity? How might a change in environmental pH due to acid precipitation or carbon dioxide pollution impact an ecosystem?
Please help explain the relationship between spontaneity, irreversibility, and entropy change. How do these terms relate, as well as how to predict one given another's condition.
Question 5 The spontaneity of a reaction depends both on the enthalpy change, Delta H, and entropy change, Delta S. Reactions that release energy produce more stable products, and the universe tends toward disorder. Thus, an exothermic reaction with a positive entropy change will always be spontaneous. Mathematically, this relationship can be represented as where Delta G is the change in Gibbs free energy and T is the Kelvin temperature. If Delta G is negative, then the reaction is spontaneous....
Under what circumstances does an enzyme catalyzed reaction rate resemble a non-enzyme catalyzed reaction? At very low concentrations of substrate (Km is greater than S) the Michaelis-Menton equation can be simplified to? At very high concentrations of substrate, the Michaelis-Menton equation can be simplified to? How do you determine the initial rate of reaction
Suppose that, in the absence of a catalyst, a certain biochemical reaction occurs x times per second at normal body temperature (37 °C). In order to be physiologically useful, the reaction needs to occur 2000 times faster than when it is uncatalyzed. Part A By how many kJ/mol must an enzyme lower the activation energy of the reaction to make it useful? Express your answer using two significant figures. PO AQ * o o ? Ea – Eac = kJ/mol
