Which of the following statements are true for BOTH the "transition state" and an"intermediate" of reaction? (This is a multi-select question, select all that apply.).Both are only observed in enzyme-catalyzed reactions.Both can be converted to product(s) or might decompose back to the reactant(s).Neither are part of the "net equation" for the reaction.Both contain covalent bonds are in the process of breaking and/or forming.Both are part of every chemical reaction. (i.e. the mechanisms of all chemicalreactions, whether enzyme catalyzed or not, will have involve both a transitionstate and an intermediate).

Transition states are not chemical species. It is simply a fleeting molecular moment during the…

When the product of reaction \\( A \\) becomes the reactant of reaction \\( B \\), the metabolic pathway is cyclic divergent bidirectional convergent linear
Consider 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?
The concept of determining which reactant is limiting and which is in excess is akin to determining the number of sandwiches that can be made from a set number of ingredients. Assuming that a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, determine the number of whole cheese sandwiches that can be prepared from 36 slices of bread and 51 slices of cheese.

Which of the following statements is false regarding an enzyme's ability to catalyse a reaction? an enzyme provides a reaction surface and a hydrophilic environment for the reaction to take place an enzyme binds reactants such that they are positioned correctly and can attain their transition-state configurations an enzyme allows the reaction to go through a more stable transition state than would normally be the case an enzyme can weaken bonds in reactants through the binding process
Consider the following chemical equation whose delta(G) = 9kcal/mol: AC + BD ---> AB + CD what are the reactants and what are the products is this reaction spontaneous? How do you know? Is energy released or consumed by this reaction? If an enzyme, which catalyzes this reaction is added, what will happen to delta (G) If this reaction is coupled to another reaction, whose delta(G) is -12 kcal/mol, what will be the net delta(G) value? will the overall reaction be spontaneous
Consider the following free energy diagram for an uncatalyzed and enzyme-catalyzed reaction. Select all the statements that are true. Without enzyme With enzyme A+B Time AB Oa. The reaction is now spontaneous due to the addition of enzyme b. The rate of the enzyme catalyzed reaction is faster than the uncatalyzed reaction O C. The reaction is exergonic O d.
