To determine: Whether the given figure illustrates an exergonic reaction or an endergonic reaction.
Introduction: The
To explain: The reason why the figure illustrates an exergonic reaction.
Introduction: The chemical reactions are of two types namely exergonic reaction and endergonic reaction. The type of reaction in which energy is released to the surrounding is known as exergonic reaction. This type of reaction is a spontaneous reaction, and the Gibbs free energy (∆G) value for this reaction is negative. The type of reaction in which energy is absorbed from the surrounding is known as endergonic reaction. This type of reaction is a non-spontaneous reaction, and the ∆G value for this reaction is positive.

Which of the following are true? (Pick two.) - Free energy Substrate Reaction progress Product AG°' 0 AG of the forward reaction > AG of the reverse reaction. AG of the forward reaction < AG of the reverse reaction.arrow_forward
- List the 6 major groups of enzymes giving an example of each in the form of an equation.arrow_forwardConsider the analogy of the jiggling box containing coins that was described on page 85. The reaction, the flipping of coins that either face heads up (h) or tails up (T), is described by the equation h ↔ T, where the rate of the forward reaction equals the rate of the reverse reaction.a. What are ΔG and ΔG° in this analogy? b. What corresponds to the temperature at which the reaction proceeds? What corresponds to the activation energy of the reaction? assume you have an “enzyme,” called jigglase, which catalyzes this reaction. What would the effect of jigglase be and what, mechanically, might jigglase do in this analogy?arrow_forwardRearrange the following terms to show the process of enzymatic reaction. Use and + to complete the equation. enzyme enzyme-substrate complex enzyme product substrate Several important things should be noted about this reaction: 1. A/an because of the fit between their structures; 2. As a result, something happens to the example, it might be split in two at a particular location. 3. Then the and 4. The enzyme is again. 5. Note that the arrows in the formula for enzyme reaction point acts on a specific to form a/an molecule. For comes apart, yielding the in the reaction and is now free to react _- This means that the reaction is 6. An enzyme-substrate complex can simply go back to the the 7. The products of an enzymatic reaction can react with the enzyme to form the and again; 8. It, in turn, may again form the 9. Therefore, the same. and the may act to cause a to go either way.arrow_forward
- Write a chemical equation for the reaction catalyzed in model one —— Chemical Reaction I wrote ( Lactase —> Glucose + Galacose ) 1. Referring to the chemical reaction you wrote for the question above is lactase a reactant or product or neither explain how you know. Q2.  describe the role of the enzyme lactase played in the reaction. Q3.) what do you think could happen to the enzyme lactase at the end of the reaction Q4.)  enzymes play a very specific roles in cells and will work on specific substrates, for example, well liked his breaks down like lactose, lipase is an enzyme that breaks down lipid molecules. Using the base and lactase examples describe how are most enzymes are named. Q5,) suppose a model of a different disaccharide sucrose would like to be able to break down sucrose explain your answer.arrow_forwardConsider the two reactions below. They are fast and have reached equilibrium by the end of the time shown. At time zero (t = 0) which is true? [Product] (M) I 2 1 Time The AG of reaction 1 is greater (more positive) than the AG of reaction 2. The AG of reaction 1 is less (more negative) than the AG of reaction 2. ○ The AG of reaction 1 is equal to the AG of reaction 2.arrow_forwardRefer to Model 10.1 and answer the question that follows What is free energy?
