Enzymes usually end in the suffix. ---------- View the full answer Transcribed image text: Which of the following statements about enzymes are true? When a piece of liver is dropped into hydrogen peroxide, the peroxide bubbles vigorously as the hydrogen peroxide decomposes into water and oxygen. the enzyme undergoes a conformational change that brings substrates closer together in an infuced. It never involves coenzymes. Enzymes are widely known to speed up reactions. Learn the definition of an enzyme, review examples, and read more about their properties and other characteristics. Which of the following is true about enzyme? He had a CBC and complete metabolic panel (CMP) completed 1 week before his visit, and the results are listed below. This makes the reaction more energetically favorable and thus more likely to occur. b. is involved in the catalytic reaction of the enzyme c. Acute hepatitis Choose the correct answer: Enzymes speed up chemical reactions by lowering A) the activation energy. DNA replication is semi conservative because one parent strand is kept intac. A. they are proteins B. they speed up the rate of chemical reactions C. they act on specific substances called substrates D. they are used up on each reaction, thus need to be produced in large q. Enzymes catalyze reactions by a. bringing the reactants together so that they can bind. b. cause enzymes to denature. a. c. will bind to the enzyme's active site, preventing binding of substrate molecules. Enzymes can lower the activation energy of reactions, but they cannot change the equilibrium point because they cannot change the net energy output. a. C- Enzymes create a chemical reaction. a. Hexokinase and G-6-PD a. c. Highest levels are seen in duchenne muscular dystrophy F.
