In NOT MORE than 350 words, distinguish between the metabolic concepts presented by the terms: i. fed state, ii. fasted state/in-between meals, and iii. extended fasting/starvation. Your response should highlight the energy status of cells under these conditions, preferred fuels, predominant metabolic pathways, and hormonal effects on cellular processes.
The dietary technique designed to increase the glycogen content in both the liver and muscles in an attempt to delay the oneset of fatigue is referred to as all of the following excpet a) glycogen loading B) glycogen supercompensation C) gluose loading D) carbohydrate loading
Discuss briefly (in less than 100 words) the practice of carbohydrate loading for endurance in aerobic exercise. What is the role of glycogen metabolism (glycogenesis and glycogenolysis) and glycolysis in carbohydrate loading? Why is this practice more productive than usual without carbohydrate loading?
(a) Differentiate TWO (2) spontaneous and nonspontaneous processes in our body metabolism with a suitable exaumple.
Endurance athletes sometimes follow the exercise-and-diet plan described here: 7 days before an event, do exhaustive exercises so as to all but deplete glycogen stores. For the next 2 to 3 days, consume few carbohydrates and do moderate- to low- intensity exercises. Finally, 3 to 4 days before the event, consume a diet rich in carbohydrates. Explain the benefits of this regime.
Which of the following describes the changes in metabolic pathways that occur during exercise? Question 12 options: a) Increased glycogenolysis b) Increased degradation of protein c) Decreased lipolysis d) Decreased gluconeogenesis
Patient who had undergone a complex maxillofacial operation could not takefood during 2 days, but glucose level in the patient's blood during that period wason the lower limit of normal. What mechanisms facilitate the maintenance ofnormal level of glucose in prolonged starvation? To answer this question:a) indicate normal fasting blood glucose level;b) draw the metabolic pathway ensuring glucose synthesis in patient's body duringa period of starvation, mark the enzymes and coenzymes;c) list the substrates of this process and its localization.
During extended fasting (≥ 4 days), what is/are the purpose(s) of tissue protein breakdown? Circle ALL that apply. a. Dispose of excess nitrogen groups so ammonia doesn't accumulate b. Provide precursors to the Liver, Kidney, Sm. Intestine for gluconeogenesis c. Provide precursors to the liver for ketogenesis d. Provide energy to the skeletal muscles through Amino Acid oxidation e. Provide energy to the liver through Amino Acid oxidation
Make a summary of metabolic disorders arising from carbohydrate metabolism. Indicate the enzyme whose absence or deficiency brings about the disorder.
Recent recommendations on diet suggestthat the sources of calories should be distributed as follows: 50%–55% carbohydrate, 25%–30% fats, and 20% protein. Suggest somereasons for these recommendations.

2. A girl decided to lose wcight and has been fasting for three days. What metabolic changes occurred in the girl's organism by the end of the 3-day fast? For answer: a) draw appropriate charts of metabolic pathways reflecting the changes in fat metabolism in the liver and adipose tissue during the prolonged fasting; b) name the hormones that accelerate these processes, and draw the charts of signal transduction of these hormoncs to the target cells; c) enumerate the regulatory enzymes with changed activity under the influence of the mentioned hormones.
