In the virtual lab, the formation of bubbles confirmed that Select one: O A. Substrate was being used up (consumed) O B. Products were being created OC. The enzyme was active O D. All of the above As you increase the amount of substrate in a reaction (while keeping the enzyme concentration the same): Select one: O A. The amount of products formed should decrease O B. The amount of products formed should remain the same. OC. The amount of products formed should increase Mixing hydrogen peroxide with an enzyme different than catalase (such as lactase) should also result in the formation of products. Select one: O True O False stion

Pls help ASAP and show all work and explanations

Which of the following is incorrect about an enzyme-catalyzed reaction? a. Its progress can be monitored as the disappearance of substrate Ob. Its progress can be monitored as the formation of product OC. The reaction rate can be expressed as the change in [enzyme] with time d. None; all the other choices are correct

Consider the following free energy diagram for an uncatalyzed and enzyme-catalyzed reaction. Select all the statements that are true. Without enzyme With enzyme A+B Time AB Oa. The reaction is now spontaneous due to the addition of enzyme b. The rate of the enzyme catalyzed reaction is faster than the uncatalyzed reaction O C. The reaction is exergonic O d. The change in free energy for the reaction is greater in the catalyzed reaction, compared to the uncatalyzed reaction e. The enzyme stabilizes the transition state for the reaction Released Energy pes

using results for experiment below conduct 1 graph of the different factors vs rate of enzyme activity. *  - after that answer this question using table and graph repfer to them as numbers (eg table 1, graph 1):   Indicate the role of manganese dioxide, sand, distilled water, pH paper, liver and potato. Is there a relationship between the independent and dependent variables?  Explain why or why not. *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%…

Which of the following is NOT a true statement about the diagram below? Intermediate A Intermediate B End-product Pathway operates 2019 Pearson Education, Inc. O O O O Substrate Enzyme 1- Allosteric site -Enzyme 2 Enzyme 3- Pathway shuts down Bound end-product Feedback Inhibition The end-product None of the other four answers (all are true statements) Each enzyme is specific for its substrate The product of each enzyme reaction becomes a substrate for the next enzyme The diagram shows a metabolic pathway serves as a competitive inhibitor of the substrate on Enzyme 1
