The majority of enzymes are fibrous proteins. Go to the next quiz: Serine Proteases. c)both non-biological catalysts and enzymes show reaction specificity. All of the following statements about enzymes are true EXCEPT: A Enzymes have unique pH and temperature optima. Enzyme function is independent of physical and chemical environmental factors such as pH and temperature. I. Dec 21, 2025 · Q- Ingestion of which of the following products may cause hypertensive crisis in patients taking MAO inhibitors? A- Carbohydrates such as starch B- Gluten-rich food C- Tyramine-rich food D- Vitamin D Practice Questions for Set 2 Cell Biology 3020 (Fall 2022) True or False: Coiled-coils are a common tertiary structure found in many proteins Which of the following amino acids is non-polar and non-charged? A. The true statement about enzymes is: B. Enzymes show very little specificity for their substrates b. enzymes are proteins D. A given enzyme is often able to regulate many different reactions. -Enzymes work generally on a broad range of substrates. The following statements describe key characteristics of enzymes: They are made of proteins. The cell envelope encases the cytoplasm and all its components. b) GTP hydrolysis results in the high affinity binding of chaperone proteins to polar amino acids on the target protein. An enzyme is never used up in a reaction. The substrate will be physically different, but not chemically different after being acted upon by an enzyme. lipids b. This is because enzymes are more specific in nature and there is a lack of formation of side products during the reaction catalysis. B) The free energy change of the reaction is opposite from the reaction that occurs in the absence of the enzyme. Enzymes are inorganic. Sep 17, 2024 · Explanation Understanding Enzymes Enzymes are biological catalysts that speed up chemical reactions in the body. The chemical make-up of an enzyme changes with each time it is used. 👉️ B. C) They lower the activation energy without being consumed. Extreme pH levels or temperatures can denature an enzyme, leading to loss of function. It is a globular protein with a quterinary structure B. Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy. This statement is true. Which of the following is true regarding enzymes? A. Digestive enzyme supplements help people with enzyme insufficiencies digest their food and absorb nutrients. Enzymes reaction rates are generally slower than other chemical catalysts e. An enzyme has an active site where its substrate or substrates bind. Which one of the following is TRUE? -Enzymes emerge changed from the reactions they catalyze. Enzymes increase reaction rates by lowering the activation energy and by interacting with substrates to facilitate reactions. The activities of enzymes are usually regulated by molecules that carry chemical signals within cells. Study with Quizlet and memorize flashcards containing terms like Which of the following statements about enzymes is not true?, In the diagram, which of the following represents the substrate of the reaction?, According to the graph, addition of amylase causes the reaction rate to and more. carbohydrates c. -An enzyme's function depends on its three-dimensional shape. Pyruvate kinase and pyruvate carboxylase are regulated by acetyl CoA in a reciprocal manner. Enzymes can only break down larger substances into smaller ones. At the end of the process, an enzyme converts a substrate into a different product. b)reactions occur at the active sight, which usually consist of a crevice on the enzyme's surface. Tyrosine C.
