Name: Hendric Nduwuba DNP and Cellular Respiration Summary https://www.youtube.com/watch?v=eLtRan2qFx0 Your assignment today is to summarize in two paragraphs (8 sentences total) the effects of dinitrophenol (DNP) on the human body. Make sure you explain what DNP is, the stages of cellular respiration, and how DNP alters the metabolism of the person using it (side effects). The following vocabulary terms need to be used: cellular respiration, adenosine triphosphate, and dinitrophenol (DNP). Your objective is to describe the role of ATP in cellular respiration in order to explain how DNP affects the rate of metabolism. The first paragraph is an introduction to the summary and the second paragraph is an explanation of the main idea. You will be graded on this criteria: main idea, explanation of cellular respiration, explanation of DNP, and paragraph structure.
Please answer the following questions 1. Give the substrate for each of the following enzymes: a. dihydrofolate reductase b. acetylcholinesterase c. lactate dehydrogenase d. DNA polymerase e. aspartate transaminase
(Biochemistry Topics: Glycolysis and Citric Acid Cycle) Why would a defect in the liver enzyme FBPase-1 result in abnormally high levels of blood lactate? Explain.
Which of these enzymes is needed to maintain a steady pool of methylene THF used in pyrimidine synthesis and cancer cells proliferation? Group of answer choices Phosphoglyceratedehydrogenase Glyceraldehydegehydrogenase Glycine decarboxylase Thymidylatesynthase
TPI deficiency is a rare human condition. Patients who lack TPI cannot convert the triose dihydroxyacetone phosphate into glyceraldehyde 3-phosphate.What happens to glycolysis in TPI patients?TPI patients suffer from chronic hemolytic anemia (abnormal breakdown of red blood cells) and have variable neuromuscular dysfunctions, including muscle weakness, poor muscle tone, and atrophy. Most die of respiratory failure during childhood. Explain why TPI-deficient patients exhibit these conditions using the diagram to justify your answer. TPI is enzyme 5.G6PD deficiency is one of the most common human genetic conditions, affecting about 40 million people worldwide. Patients suffer from hemolytic anemia when exposed to certain drugs, viral or bacterial disease, or fava beans.
Red blood cells synthesize and degrade 2,3-biphosphogylerate (2,3-BPG) as a detour from the glycolytic pathway, as shown in the figure.2,3-BPG decreases the oxygen affinity of hemoglobin by binding in the central cavity of the deoxygenated form of hemoglobin. This encourages delivery of oxygen to tissues. A defect in one of the glycolytic enzymes may affect levels of 2,3-BPG. The plot above right shows oxygen-binding curves for normal erythrocytes and for hexokinase and pyruvate kinase-deficient erythrocytes. Identify which curve corresponds to which enzyme deficiency.
Hemoglobin 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.
The main location of ethanol metabolism in the body is the liver and the main route of detoxification includes liver alcohol dehydrogenases (ADH) located in the cytosol and aldehyde dehydrogenases (ALDH) located in the mitochondrion. Together these sequentially convert ethanol into acetate. A second (more minor) route of detoxification includes the microsomal ethanol oxidizing system (MEOS). 1. Based on the chemical structure, predict how permeable a biological membrane will be to ethanol (in the absence of a transporter/channel)?
What are four benefits of anaerobic glycolysis in tumor cells? https://www.nature.com/articles/s41598-019-40617-3#Tab1
What is the role of 2, 3-Bisphosphoglycerate (2,3-BPG) in the function of haemoglobin as an oxygen carrier molecule? Explain the binding mechanism and effect of 2,3-BPG leading to the reduced oxygen binding affinity for haemoglobin and transitions in the T (deoxygenated) and R (oxygenated) states of haemoglobin.
Propionic acidemia has a relatively high prevalence in South Africa, among both black and white families. This fatal disease is often diagnosed by the elevated presence of propionyl carnitine, propionylglycine and methyl citrate in blood and urine. Discuss the metabolism involved and origin of these markers.
The Warburg effect is where tumor cells preferentially catabolize glucose to lactate even in the presence of oxygen (aerobic glycolysis), whereas normal cells preferentially catabolize glucose to carbon dioxide (oxidative phosphorylation). Treatment of tumor cells with the lactate dehydrogenase inhibitor NCI-737 blocks ATP production. Which of the following statements about NCI-737 treated tumor cells are MOST correct? 1) AGglycolysis is negative 2) AGglycolysis is positive 3) AG" for glycolysis is negative 4) AG" for glycolysis is positive 5) NAD+/NADH decreases 6) NAD+/NADH increases 1, 4, 6 1, 3, 5 2, 4, 6 2, 3, 6 2, 3, 5
