several factors that affect the reaction rates of enzymes are temperature,PH,enzyme concentration,substrate concentration and also the presence of inhibitors and activators
List 3 factors that affect the reaction rates of enzyme catalyzed physiological reactions.
factors affecting rates of enzyme-catalyzed reactions; identify and describe
Temperature can affect enzyme-catalyzed reaction rates. What is the temperature option for trypsin? What would happen if the experiment was done at trypsin’s optimum pH but at 4 degrees celsius? 50 degrees Celsius? 100 degree Celsius?
List and describe the factors that can affect enzymatic reactions. a. Substrate Concentration b. Enzyme Concentration c. pH d. Temperature e. Cofactors f. Inhibitors (I have them listed but do not understand their affects)
7. Biological redox reactions are catalyzed by enzymes requiring stoichiometric co-factors. In the case of the oxidation shown below, the cofactor is derived from the vitamin riboflavin. Draw a mechanism for the reaction shown in the scheme. enzyme O FAD FADH2 enzyme succinate dehydrogenase 7. Biological redox reactions are catalyzed by enzymes requiring stoichiometric co-factors. In the case of the oxidation shown below, the cofactor is derived from the vitamin riboflavin. Draw a mechanism for the reaction shown in the...
3. "Enzymes affect reaction rates, not equilibria." This is a fundamental concept of enzyme action. Explain, in your own words, why enzymes cannot alter the equilibrium of a reaction. Then explain how enzymes can actually speed up a reaction. 4. How is the activation energy AG different from the biochemical standard free energy change AG"? 5. Explain why AG's p can be different from AG p.s. Describe the implication of this difference in terms of the direction of the reaction...
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...
s- (3 pts) The flowing rates have been an enzyme- catalyzed reaction at various substrate concentrations: Run no. 103 [S]M Rate, v/ (Ms') 2.41 3.33 4.78 6.17 7.41 9.52 0.0 12.5 0.4 0.6 4 2.0 4.0 a- From Line-Weaver double reciprocal plot, obtain and Mechaelis-Menten constant, max b- If the enzyme concentration is 1.00 x 10-11 M calculate kz.
Which statement characterizes an enzyme catalyzed reaction? Enzymes change the reaction equilibrium Enzyme-substrate binding is irreversible Enzymes do not increase reaction rates Enzymes increase reaction rates Enzymes defy the space-time continuum
Many uncatalyzed reactions are slow under physiological conditions. One of the most striking characteristics of enzymes is their catalytic power, which is the ratio of the catalyzed reaction rate constant, kaat, to the uncatalyzed reaction rate reaction constant, kuncat The reaction catalyzed by enzyme A has an uncatalyzed reaction rate constant of 0.18-1 Use the graphs to calculate the catalytic power of enzymes A and B. Enzyme A catalytic power of enzyme A at pH 7: 500000 1,000,000 900,000 800,000...
