Introduction: (4 pts) (Answer questions in paragraph form - 300 words max) What are enzymes and what do they do? What are the optimal conditions for an enzyme? What factors affect enzyme activity and how? How is the structure of an enzyme related to its function? What is amylase? What reaction does it catalyze? Research the amylase enzyme you used (organism) and the optimal conditions of temperature, pH, or salt, it requires. Explain why DNS is used and why it is important for determining enzyme activity. Cite and reference your sources using APA style.
Reminder: Enzymology is foundational to biochemistry. You should review and be familiar with the enzymes unit from BICH410. Here is a sample question as review!! Which of the following characteristics is(are) accurate in describing a regulated enzyme? Select all that apply. a) always responds the environment by covalent modification by phosphorylation b) displays only negative cooperativity c) contains multiple subunits d)has a defined T state and R state
Select true if the statement is CORRECT and false if OTHERWISE 1. Enzymes are catalysts and increase the speed of a chemical reaction without themselves undergoing any permanent chemical change. 2. Catalysis is defined as the acceleration of a chemical reaction 3. if the amount of the enzyme is kept constant and the substrate concentration is then gradually increased, the reaction velocity will decrease. 4. In the Induced-fit Model, if a dissimilar substance which does not fit the site is present, the enzyme rejects it 5. The Michaelis constant Vo is defined as the substrate concentration at 1/2 the maximum velocity. 6. A prosthetic group - an organic substance which is dialyzable and thermostable which is firmly attached to the protein or apoenzyme portion. 7. The rate of an enzyme-catalyzed reaction increases as the temperature is raised beyond optimum temperature. 8. Enzymes can be classified by the kind of chemical reaction catalyzed. 9. The living cell is the site of tremendous…
NO AI GENERATED RESPONSE I NEED EXPERTS!! using results for experiment below conduct 1 graph of the different factors vs rate of enzyme activity. * *NO FUNNEL GRAPHS ACTUAL GRAPH WITH GOOD TITLE , AND MAKE SURE IT LOOKS LIKE THE IMAGE I PLACED BELOW** important info: experiment procedure: The experiment began by preparing a hot water bath by boiling water and an ice water bath using ice in a 400 mL beaker. In the control group, 2 mL of 3% H2O2 was placed in a test tube and a pinch of MnO2 was added. The rate of this reaction was assigned as 5, and the production of bubbles in millimeters (mm) was noted. The reaction was considered complete when no more bubbles were produced. Another control group was set up by placing 2 mL of 3% H2O2 in a test tube and adding a pinch of sand, with the rate of reaction assigned as 0. To investigate the difference between plant and animal catalase, 2 mL of H2O2 was added to a test tube and a small piece of fresh liver was added. The rate of…
TRUE OR FALSE 25. The Lineweaver-Burk plot shows a linear pattern of product formation. 26. Generally, inhibitors form covalent bonds with the active site. 27. The binding of the enzyme to its subs
Lab Exercise 10C, the purpose of adding NaCl (table salt) to Pizza Dough is to: a. catalyze oxidation of fatty acids to lactic acid b. carry H2 reducing equivalents during the baking process c. hydrolyze alcohol so that it does not accumulate in the dough d. tighten cross-linkages in the gluten matrix making the dough more elastic and chewy e. control how fast yeast cells produce CO2 during the leavening process
22. What is a major benefit of calculating catalytic efficiencies? Group of answer choices It determines whether a catalytic reaction is cooperative It allows you to compare different substrate preferences for an enzyme It tells you the rate of an enzyme reaction It allows you to determine the efficiency of the enzyme being studied

What are the values of Vmax and KM in the absence of inhibitor? In its presence? In its presence? What is the type of inhibition?
40. Which of the following statements about transition state analog inhibitors are true? MARK ALL THAT APPLY. Group of answer choices Provide insight into catalytic mechanisms. Very potent and specific inhibitors. They have difficulty binding to the active site because they resemble the energetically unstable transition state of the substrate. Can be used as immunogens to generate catalytic antibodies.
Help please. This question is specifically asking for the identification of the biomolecules that are attached to the sphingosine core, then we need to answer what bond causes those biomolecules to be connected to the sphingosine, what reaction created that bond (maybe addition or oxidation etc.), what were the starting materials and lastly what reagents or conditions are needed for the reaction to occur. Thank you!
An enzyme has a rate enhancement of 1.3x106. Calculate the value of ΔΔG‡ at 25.0 °C in kJ mol-1. (Hint: be sure to pay attention to units and signs.) (R = 8.3145 J mol-1 K-1)
45. Which of the following is/are true? (MARK ALL THAT APPLY) Group of answer choices Enzymes lower the activation energy of the reaction Enzymes bind more strongly to the substrates than the transition state of the reaction Enzymes alter the standard free energy of the reaction. Enzymes force reactions to proceed in only one direction. Enzymes alter the equilibrium of the reaction. PreviousNext
