NO AI GENERATED RESPONSE I NEED EXPERTS!! using results for experiment below conduct 1 graph of the different factors vs rate of enzyme activity. * *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% H2O2 in a test tube and adding a pinch of sand, with the rate of reaction assigned as 0. To investigate the difference between plant and animal catalase, 2 mL of H2O2 was added to a test tube and a small piece of fresh liver was added. The rate of…
9:34 AM You sent Help me with this one Select true if the statement is CORRECT and false if OTHERWISE 1. Enzymes are catalysts and increase the speed of a chemical reaction without themselves undergoing any permanent chemical change. 2. Catalysis is defined as the acceleration of a chemical reaction 3. if the amount of the enzyme is kept constant and the substrate concentration is then gradually increased, the reaction velocity will decrease. 4. In the Induced-fit Model, if a dissimilar substance which does not fit the site is present, the enzyme rejects it 5. The Michaelis constant Vo is defined as the substrate concentration at 1/2 the maximum velocity. 6. A prosthetic group - an organic substance which is dialyzable and thermostable which is firmly attached to the protein or apoenzyme portion. 7. The rate of an enzyme-catalyzed reaction increases as the temperature is raised beyond optimum temperature. 8. Enzymes can be classified by the kind of chemical…

Summaries of two clinical case studies follow. For each case determine which enzyme isdefective and designate the appropriate treatment, from the lists provided at the end of theproblem. Justify your choices. Answer the questions contained in each case study. 15 marksCase A The patient complains of painful muscle cramps when performing strenuous physicalexercise but has no other symptoms. A muscle biopsy indicates a muscle glycogen concentrationmuch higher than normal. Why does glycogen accumulate?Case B The patient is lethargic, her liver is enlarged, and a biopsy of the liver shows largeamounts of excess glycogen. She also has a lower than normal blood glucose level. What is thereason for the low blood glucose in this patient?
