Biochemistry

It should be noted that the hormone thyroxin, which is produced in the thyroid gland in excessive quantities, significantly affects oxidative phosphorylation, introducing an imbalance in the processes of oxidation and ATP formation. It interrupts the path of electron transfer through a system of cytochromes and prevents the formation of ATP. Therefore, in people with hyperthyroidism, an excess of heat is formed, which manifests itself in elevated body temperature. QUESTIONS AND TASKS: 1. What is the role of biological oxidation for the vital processes of the body ? 2. What are the differences between biological oxidation and oxidation in inanimate nature? 3. What are the groups of enzymes involved in biological oxidation? 4. What is the structure of anaerobic and aerobic dehydrogenases? 5. Describe the role of hemin enzymes in biological oxidation. 6. How are electrons and protons transported in biological oxidation? 7. Describe the differences between tissue respiration and oxidative phosphorylation. 8. What substances are the final products of biological oxidation? 9. What is the difference between the oxidized forms of NAD and FAD from the reduced ones? 10. What vitamins are involved in the construction of dehydrogenases? 11. What are the ways to use energy in the body? 12. What is ATP? Where it is formed, its structure and function? 13. What is the difference between substrate phosphorylation and oxidative? 14. With an increase in thyroid function, heat generation sharply increases, and body temperature rises. What biochemical processes determine this phenomenon? 115
