Which of the following is NOT true about enzymes? Enzyme inhibitors interact reversibly or irreversibly with an enzyme to alter its Km and /or Vmax values. Enzymes typically act under milder conditions of temperature and pH than non-enzyme chemical catalysts. Zymogens are the inactive precursors of enzyme. Nucleophilic groups can catalyze reactions through the transient formation of covalent bonds with the substrate. Transition state stabilization can significantly increase the activation energy for a reaction.
Which of the following describe what enzymes such as Chymotrysin accomplish to allow products to form and be released by the enzyme active site? Group of answer choices catalyze chemical eactions that are thermodynamically unfavorable to occur establish a more stable transition state at a higher energy level to perform a catalysis reaction redce the chemical energy held within a chemical bond modify chemical structure of a substrate to "fit" within the active site
Choose only the letter, no explanation needed. Enzyme activity is affected by a variety of factors. What factor causes the enzyme to denature if it becomes extremely high? * Choices: A. Water's Effect B. pH C. Temperature D. Activator's Effect An inhibitor binds to the enzyme's active site, preventing the substrate from binding to it. What conclusions can you make from this situation? * A. No reaction occurred B. Non-competitive inhibition occurred C. Enzyme activity occurred D. Competitive inhibition occurred Each enzyme is very selective when it comes to its substrate. What can you conclude from this statement? * A. Any substrate can bind to the active site. B. Enzymes are used up in the reaction. C. Only a specific substrate can bind to the active site. D. Enzymes break down when not used. Lock : Key :: Active Site : _____________________________ * A. Substrate B. Active Site C. Coenzyme D. Cofactor Enzymes only speed up biological functions, so they are NOT used up in the…
Which of the following statements is not true about enzymes?* A. Enzymes are biological catalysts B. Enzymes as catalysts lowers the activation energy thus, speeds up the rate of reaction C. Enzymes are proteins D. Enzymes are highly specific E. None of the given options
Which of the following do enzymes change?∆G ; reaction rate; types of product generated; activation energy; the laws ofthermodynamics.
Find an enzyme that is used by humans for some industrial or useful process (apart from its original purpose; e.g. food production, textiles, agriculture, clinical diagnosis, medical treatment, biofuel production, material polymerization, etc.). How do we obtain or harvest the enzyme? What reaction(s) does it catalyze, and how is this useful for its industrial purpose? 200 words only
Which of the following does NOT describe enzyme-catalyzed rate acceleration derived from the binding of substrate to enzyme a. repulsion between like charges b. substrate proximity and orientation c. reduction of entropy (increased order) d. desolvation of the substrate by the enzyme active site e. introduction of strain in bonds that need to break
Which of the following statements about enzyme character-istics is true?(a) Enzymes generally exhibit a high degree of specificityfor one particular substrate.(b) Enzyme-substrate complexes occur when a substratemolecule collides with the allosteric site of an enzyme.(c) Chemical bonds within a substrate are strength-ened when this substrate forms an enzyme-substratecomplex.(d) Enzymes have a region called the active site, which pro-vides an area where it can form a loose association withits substrate.(e) a and d.
Define the following terms:a. catalystb. transition statec. substrated. activation energye. active site2. Define the foll
What are the steps for an enzyme to create a product in order: The energy of activation is lowered so the reaction can happen quicker. Substrate attaches to the active site. The product is created and released from the active site. The energy of activation is lowered so the reaction can happen slower. A specific substrate attaches to the active site.
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.
What type of inhibition is occurring when the end product stops the action of the first enzyme in the video on feedback inhibition found below: https://www.youtube.com/watch?v=qHb7iieM2Ro Select one: a. competitive b. non-competitive c. Both competitive and non-competitive inhibition are illustrated in this video/figure
