- An organelle present in animal cells but missing from plant cells is: BblGepure onuH oreer: a. Avacuole b. Anucleolus c. Acentriole d. A mitochondrion
- 4. Illnhibitory neural circuits: feed-forward reciprocal, recurrent,lateral inhibition Their functions.
- 8. The source of maltose in the intestine is activity: -amylase y-amylase sucrase -isomaltase complex isomaltase B-glycosidase complex
- 11. Indicate the redox pairs : (indicate one or more answers) thiamine / thiamine diphosphate NADP^+/NADPH+H^+ ADP/ATP NAD^+/NAD+H^+ FAD/FADH_(2)
- 1. In diseases of internal organs - heart and liver - along with other biochemical parameters, the activity of LDH isoenzymes (lactate dehydrogenase) is investigated. Explain why?What class does this enzyme belong to? What type of reactions does it catalyze? 2. A 45-year-old man was admitted to the clinic complaining of severe epigastric pain with irradiation in the back , accompanied by vomiting During the examination , high activity of alpha amylase and trypsin was detected in the blood High amylase activity is detected in urine. Specify the pathology associated with these changes. 3. Glucose penetrates into skeletal muscles slowly, and its concentration in them is low - about 0.01-0.1 mM. Why is the enzyme hexokinase preferable to glucokinase for glucose activation under these conditions? 4. The patient suffers from muscle cramps during strenuous physical work, but otherwise feels healthy. A biopsy of the muscle tissue revealed that the concentration of glycogen in the muscles of this patient is much higher than normal . Why does glycogen accumulate? How can we prevent cramps at work? 5. A child of the first year of life was given sweet fruit juice for the first time. Some time after that, he started vomiting and convulsing. What could be the reason for their occurrence? What advice should parents give? 6. The content of ketone bodies in the patient's blood and urine is sharply increased. What is the name of this condition and when does it occur? 7. When examining the patient, the doctor noted multiple petechiae on the body, an increase in the size of the spleen and liver. In the blood, the activity of ebrosidase was 1.4nmol/mgast h (norm 4.7-19.0 ). What kind of disease can be diagnosed in a patient? What treatment will the doctor prescribe? Justify the answer. 8. Statins are highly effective hypocholesterolemic drugs . What is the mechanism of their action based on? 9. One of the methods of treatment of cholelithiasis is associated with prolonged administration of henodeoxycholic acid into the patient's body. How can the therapeutic effect of this drug be explained? 10. The patient was admitted to the clinic complaining of abdominal pain that occurs after eating, especially fatty food Laboratory analysis: blood serum is cloudy throughout the entire volume of the test tube. When standing in the refrigerator for 10 hours, a cloudy creamy top layer formed the serum is transparent under the layer. The TAG level is 9.9mmol/1 (norm: 0.5-2.0mmol/l) . The activity of serum LPL (lipoprotein lipase) is 0.0 units. Evaluate the results of the research. What are the biochemical disorders underlying this disease? Is the risk of atherosclerosis increased in this patient?
Помощь с домашним заданием по биологии
Самая сложная часть изучения биологии — как помочь учащимся понять микроскопический мир биологии, как проникнуть внутрь клеток и исследовать гены и молекулы. Однако с развитием информационных технологий помощь в выполнении домашних заданий по биологии может сыграть важную роль, когда ни слова, ни изображения не могут полностью объяснить вопросы биологии.
ВопросAI — это онлайн-программа для изучения биологии, которая помогает вам изучать и осваивать знания по биологии, включая разнообразные эксперименты и соответствующие упражнения, что принципиально отличается от обычного помощника по вопросам биологии. Здесь вы можете моделировать эксперименты, чтобы воспроизвести экспериментальные сценарии, от мелкого до глубокого, слой за слоем, чтобы изучить и понять точки зрения.
