Which of the following statements does not hold true for restriction enzyme ? An increase in temperature can stop the reaction by denaturing the enzyme. (a) Enzymes are mostly proteinous in nature. c) Enzymes are proteins. An enzyme is not consumed by the catalytic process. Option 1) Enzymes are mostly proteinous in nature. Which of the following statements regarding enzyme function is false? can transfer reactive groups from one substrate to another. Which of the following statements about enzymes are correct? An enzyme lowers the activation energy of a chemical reaction. The enzyme is a biocatalyst b. b. a) Enzymes can initiate chemical reactions. a. Option 3) Enzymes are denaturated by ultraviolet rays and at high temperature. localize substrates near one another. (d) Enzymes are least reactive at optimum temperature. (c) Enzymes are denaturated by ultraviolet rays and at high temperature. e) Enzymes … Almost all enzymes consist of proteins (some consist of RNA, but that does not make the statement incorrect) Enzyme activity is affected by pH changes, as a change in pH can help an enzyme act faster, until it passes the optimum point. (ii) Enzymes are proteins whose three dimensional shape is key to their functions. Enzymes can be used to accelerate both anabolic and catabolic reactions. Enzymes: lower the activation energy of chemical reactions. B. Enzymes are very specific for certain substrates. Which of the following statements about enzymes is incorrect? (Concept 8.4) Most enzymes are proteins. (iv) Enzymes are highly specific for reactions. C. Enzymes can be denatured. Enzymes speed up chemical reactions by helping to orient molecules and providing them with a … C. Enzymes are used up when they catalyze a chemical reaction, so must be synthesized for each new chemical reaction. Which one of the following statements is incorrect about enzyme catalysis? After that point, the enzyme denatures. Enzymes can initiate or start a chemical reaction by stressing or bending a the chemical bonds of the substrate, for example. Option 2) Enzyme action is specific. An enzyme is consumed during the reaction it catalyzes. 2. ... Succinylcholine must be an allosteric regulator for this enzyme. enable two substrates to interact that would never interact without the enzyme present. c. Question: Which Of The Following Statements About Enzymes Is FALSE?a. Enzyme increases the rate of reaction c. Enzyme decreases the activation … Which one of the following statements is incorrect about enzyme catalysis? Which of the following statements about enzymes is incorrect? An enzyme is very specific in terms of which substrate it binds to. c. Enzymes generally remain unchanged after finishing catalyzing B) The core enzyme contains several different subunits. An increase in temperature can increase the reaction rate by increasing the speed at which molecules move. Option 4) Enzymes are least reactive at optimum temperature. can put a strain on substrate molecules to make reactions more efficient. d) Enzymes contain an active site for binding of particular substrates. (iii) Enzymes speed up reactions by lowering activation energy. Which of the following statements concerning the effect of temperature change on an enzyme-catalyzed reaction is incorrect? Which of the following statements about enzymes is incorrect? The active site must have the wrong configuration to … Most enzymes are proteins. b) Enzymes speed up chemical reactions. | C. Proteins are a main source of energy for cells. (i) Enzymes do not alter the overall change in free energy for a reaction. (c) It is isolated from viruses (d) It produces the same kind of sticky ends in different DNA molecules (b) Enzyme action is specific. A. (a) It recognises a palindromic nucleotide sequence (b) It is an endonuclease . An enzyme's function depends on its three-dimensional shape. Which of the following statement/s is/are correct? D) During digestion the essential macromolecules are directly absorbed. a. Which one of the following statements about enzymes is incorrect? Section 2.18 b) No, this is a correct statement.
