A patient is on a drug for a long time ("LKM A"). When inserting "LKM B", a drug interaction occurs. Which of the following alternatives describes a drug interaction where the levels of free "LKM A" in the blood are expected to increase? Select an alternative:
CYP enzyme inhibition
Inhibition of uptake transporter for "LKM A" in the gastrointestinaltract
Increased secretion of "LKM A" in the gastrointestinal tract
CYP enzyme inductionComplex binding
Hypoglycemia comes about for various reasons and clinic symptoms usually occur at blood glucose concentrations:
A.
Hemoglobin molecules exposed to high levels of glucose are converted to glycated products. The glycated product used to measure blood glucose control in diabetics is hemoglobin A1C (HbA1C), contained in red blood cells that last around 3 months. In general terms, explain how HbA1C forms and why it is a useful marker for blood glucose control.

- List three indicators that a supplement might actually change metabolic physiologyarrow_forwardAt the conclusion of anaerobic glycolysis, a metabolite is formed (you should have mentioned this in part g of question 6 above) that is released into the general circulation. Briefly describe this process and the fate of this metabolite. What would be the expected difference in this metabolite between two individuals of differing fitness levels (e.g., one athlete has a higher VO2max than the other) during an exercise test?arrow_forwardHemoglobin molecules exposed to high levels of glucose areconverted to glycated products. The most common, referred to as hemoglobin A1C (HbA1C), contains a b-chain glycatedadduct. Because red blood cells last about 3 months, HbA1Cconcentration is a useful measure of a patient’s blood sugarcontrol. In general terms, describe why and how HbA1Cforms.arrow_forward
- If the metabolite is an active drug what will happen to the efficacy of the drug following saturable hepatic metabolism given at a high dose? Is it desirable or not?arrow_forwardHemoglobin glycation (so named to distinguish it from glycosylation, which is the enzymatic transfer of glucose to a protein) is a non-enzymatic process that involves reaction of the N-terminal amino group of hemoglobin and glucose. The amount of glycated hemoglobin (GHB) is usually about 5% of total hemoglobin (and corresponds to a blood glucose concentration of 120 mg/100 mL). However, in people with untreated diabetes this value may be as high as 13%, which indicates an average blood level of about 300 mg/100 mL -dangerously high. One of the aims of insulin therapy is to maintain GHB values of about 7%. Draw a possible chemical scheme for the glycation of hemoglobin.arrow_forwardNon-alcoholic fatty liver disease has been linked to high-sugar diets. Explain?arrow_forward
- Define the following terms:a. ketosisb. ketoacidosisc. osmotic diuresisd. GLUT4e. body mass indexarrow_forwardCoenzyme Q-10 (Ubiquinone) is one of the most important and crucial substances within the human body. The heart muscle normally has very high levels of CoQ-10, and when these levels drop by 75%, it will stop pumping. When CoQ-10 (Ubiquinone) levels drop by 25% within the body, diseases usually occur. Why does this happen?arrow_forwardA patient complains about low body temperature, weight gain, lethargy, drowsiness. T3 and T4 concentration are decreased in blood plasma. What disease is Characterized by these symptoms? What changes in biochemical processes can cause the development of the mentioned symptoms? Explain.arrow_forward
- For each of the following examples, indicate whether the drug is acting on physical process, chemical process or enzymatic system (your answer should be only; Physical, Chemical or Enzymatic). A. A drug is used as an antidote in lead poisoning and acts by binding to lead particles in body (chelation therapy). B. A drug acts to reduce flatulence and acts by reducing the surface tension of intestinal gas bubbles in the GI tract (e.g. Simethicone). C. A drug competes with alpha-glucosidase in intestine to reduce glucose conversion from disaccharides (e.g. Acarbose).arrow_forwardOxygen is transported from your lungs to tissues throughout your body by red blood cells. Approximately 2.4 million new red blood cells are produced per second in human adults. The functional lifetime of a red blood cell is about 100-120 days, during which time the red blood cells are continually moved by the blood flow. Which of the following enzyme deficiencies could possibly cause hemolytic anemia due to breakdown and loss of red blood cells? Isocitrate dehydrogenase, a Krebs cycle enzyme Pyruvate kinase, a glycolysis enzyme Succinyl-CoA synthetase, a Krebs cycle enzyme Ubiquinone oxidoreductase, complex I of the electron transport chainarrow_forwardB) Read the situations below and indicate which of the four methods of enzyme regulation is occurring for each. a) The energy-carrying molecule ATP is made by the enzyme ATP synthase. Muscle cells use a lot of energy and also have higher amounts of the ATP synthase enzyme than many ouier cem types. General mechanism of enzyme regulation: /1 b) Prostaglandins are messenger molecules involved in the inflammatory response, as well as th perception of pain. They are synthesized from polyunsaturated fatty acid substrates by an enzyn called cyclo-oxygenase. "Ibuprofen" is the active ingredient in a variety of anti-inflammatory medications such as Motrin® and Advil®. It reduces pain and swelling by binding to a hydrophobic channel in the active site of cyclo-oxygenase, blocking the polyunsaturated fatty acids from binding to the enzyme, and therefore stopping production of prostaglandins. General mechanism of enzyme regulation: a) In point form, describe the steps by which ATP is produced…arrow_forward
