- How does the average reaction rate differ from an instantaneous reaction rate? © A. The average reaction rate is how quickly the reaction proceeds over time. An instantaneous reaction rate is how quickly the reaction proceeds at a specific time. B. The average reaction rate is how quickly the reaction proceeds at a specific time. An instantaneous reaction rate is how quickly the reaction proceeds over time. C. The average reaction rate is how quickly the reaction proceeds over time considering the reactants. An instantaneous reaction rate is how quickly the reaction proceeds at a specific time considering the products. D. The average reaction rate is how quickly the reaction proceeds over time. An instantaneous reaction rate is how quickly the reaction proceeds compared to another reaction.Drag and drop the statements to the correct box: Enzymes DO: Decrease required activation energy Enzymes DON'T: Remain unchanged during the reaction Increase the reaction rate Energy Change the products made Activation energy (X+Y) reactants Change the reactants used Activation Energy A Activation energy (Y→X) products ΔΗ Reaction path Reaction without catalyst Reaction with catalyst Name two things we learned that can denature an enzyme:Which of the following steps should be followed when performing kinetics experiments? Choose all that apply, partial positive and negative mark are given for correct and incorrect answers. enzyme concentration is kept constant for all reactions the enzyme and substrate should be mixed only when the reaction is initiated (when the absorbance readings are taken) the michaelis constant must be known reaction rates must be taken until reaction completion
- Briefly discuss each of the three reaction types we learned. What are their differences? Similarities?What condition must be met for a reaction to take place? Hydration: Hydrogenation: Dehydration:The line does not cross the X-axis when the Y-variable is equal to zero 1점 because * Why does this line not start exactly at (0,0)? Rate of Reaction Enzyme Concentration the low concentration of enzyme is still enough to catalyze some reaction some small amount of product can be formed even without the enzyme present some small amount of product can be formed even without any product the pH was changedWhich of the following are effects of catalyst that cause an increase in the rate of reaction? (This is a multi-select question. Select all that apply). a decrease in DG‡. an increase in DG. an increase in temperature. an increase in the energy of the molecules/ions of reactant. an increase in the number of molecules/ions of reactant with enough energy to overcome the activation energy barrier.

O O O O Substrate Enzyme 1- Allosteric site -Enzyme 2 Enzyme 3- Pathway shuts down Bound end-product Feedback Inhibition The end-product None of the other four answers (all are true statements) Each enzyme is specific for its substrate The product of each enzyme reaction becomes a substrate for the next enzyme The diagram shows a metabolic pathway serves as a competitive inhibitor of the substrate on Enzyme 1Which of the following is not an assumption made when evaluating Michaelis Menton kinetics? the reaction is happening at body temperature the substrate is in great excess of the catalyst measurement of initial velocity of the reaction reaction conditions are occurring under steady stateMark any/all statements that are TRUE regarding reactions and enzyme catalysis. Group of answer choices -The role of an enzyme in catalysis is to increase the difference in free-energy between the products and reactants (increase the G for the reaction). -None of these is correct. -The free-energy of a reaction (G) determines the rate of reaction. -In thermodynamics, the term "spontaneous" means that a reaction requires energy to proceed. -The transition state of an enzyme-catalyzed reaction is destabilized in comparison to the transition state of the uncatalyzed reaction.
- this one represents an endothermic reaction. Things are similar: the flat line on the left (beginning of the reaction) is the total energy possessed by the reactant molecules; once again, kJ stands for energy in kiloJoules, thousands of Joules. The flat line on the right (reaction complete) is the total energy of the products. Since an endothermic reaction has a net absorption of energy (taking this extra energy from the surroundings), the products have higher energy than the reactants. Question: the energy of the reactant molecules is kJ. [to answer, simply identify the correct y-axis coordinate.] 250 200 PE (kJ) 150 100 50 Reaction pathwayI need help with a biology question, Choose the letter of the best match from the following: 1.The reactant on which the enzyme works A. Substrate, 2. Allosteric inhibibitor binds here; changes enzyme shape B. Non-catalytic binding site 3. spot on the enzyme where the reactant binds and is changed into product C. Active site 4. part of the complete enzyme complex; a non protein, organic component D. CoenzymeA group of students is conducting a lab investigation on a chemical reaction. An enzyme is present during the chemical change, and the reaction rate is recorded at various temperatures. Their results are graphed below.
