8. In a patient with anemia, the presence of Heinz bodics in the RBCS was the result of the hemoglobin subunits aggregation due to the oxidation of -SH groups of Hb cysteine residues with active oxygen forms and the formation of disulfide bonds. What metabolic disorders in the RBC can be the cause of this clinical case? To solve the problem: a) indicate which reactions maintain cysteine residues in a reduced state; b) name the coenzyme involved in this process, write a diagram of the process in which the reduced form of this coenzyme is formed; c) indicate the enzyme which deficiency may lcad to a lack of the reduced cocnzyme and be the cause of the clinical case described above.

3.) Tumors & Lactate. When tumor cells spread to regions of the body with low oxygen levels, the tumor cells generate adenosine triphosphate (ATP) from breaking down glucose into lactate. This is called the Warburg theory of cancer. How do DNA mutations that are present in these tumor cells enable them to thrive in low and high oxygen microenvironments? Write down your hypothesis. Glucose CYTOSOL Glycolysis Pyruvate No O, present Fermentation O, present Aerobic cellular respiration MITOCHONDRION Ethanol, lactate, or other products Acetyl CoA CITRIC ACID CYCLE A Figure 9.18 Pyruvate as a key juncture in catabolism. Glycol- ysis is common to fermentation and cellular respiration. The end prod- uct of glycolysis pyruvate, represents a fork in the catabolic pathways of glucose oxidation. In a facultative anaerobe or a muscle cell, which are capable of both aerobic cellular respiration and fermentation, pyru- vate is committed to one of those two pathways, usually depending on whether or…
