Question 3: Your book reports that a normal blood glucose level is from 60 to 110 milligrams per deciliter. Determine the minimum and maximum masses of glucose in the blood of a person with a blood volume of five liters. • Explain the changes shown in the graph: Insulin Glucagon Blood glucose Liver glycogen 12-24 Hours of starvation Draw the structures the compounds commonly referred to as "blood ketone bodies." Two of them are ketones, but one of them actually isn't. Which one, and why is it included with the others? Relative change Free fatty acids

Triacylglycerols, with their hydrocarbon-like fatty acids, have the highest energy content of the major nutrients. (a) If 15% of the body mass of a 70.0 kg adult consists of triacylglycerols, what is the total available fuel reserve, in kilojoules and kilocalories, in the form of triacylglycerols? Recall that 1.00 kcal = 4.18 kJ. (b) If the basal energy requirement is approximately 8,400 kJ/day (2,000 kcal/day), how long could this person survive if the oxidation of fatty acids stored as triacylglycerols were the only source of energy? (c) What would be the weight loss in pounds per day under such starvation conditions (1 lb = 0.454 kg)?
Calculate the free energy change for glucose entry into cells when the extracellular concentration is 4.5 mM and the intracellular concentration is 2.1 mM at 37oC. Express your answer in kJ/mol. ___KJ/mol
In type II diabetes, insulin is produced but is nonfunctional. These patients are described as starving in a sea of plenty, because their blood glucose levels are high, but none of die glucose is transported into the cells. Describe how this leads to malnutrition.
Calculate the free energy change for glucose entry into cells when the extracellular concentration is 4.5 mM and the intracellular concentration is 2.1 mM at 37oC. Express your answer in kJ/mol.
When glucose goes through the steps of cellular respiration, the overall process can be summarized as the oxidation of glucose. Question 4 options: True False
The typical human adult uses about 160 g of glucose per day, 120 g of which is used by the brain. The available reserve of glucose (~20 g of circulating glucose and ~190 g of glycogen) is adequate to sustain the individual for about one day. After the reserve has been depleted during starvation, how would the body obtain more glucose?
Please answer all the three questions. 1)Explain and rank glycogen, amylose, amylopectin, and cellulose in lightest to darkest color after iodine test. 2) How can you experimentally determine with HCl and NaOH the PHi? 3)What is the effect of ethanol on glucose metabolism?
Discuss the relative effectiveness of dieting and exercise in losing weight noting that most athletic activities consume food energy at a rate of 400 to 500W while a single cup of yogurt can contain 1360KJ (325 kcal) specifically is it likely that exercise alone will be sufficient to lose weight? You may wish to consider that regular exercise may increase the metabolic rate, whereas protracted dieting may reduce it
Discusskey impairments that are characteristic in the altered glucose metabolism of people with Type 2 Diabetes. (note: you should describe effects in different key organs/tissues involved in glucose metabolism within your answer) As a result of these impairments, describethe expected differences in post-prandial metabolism of a given load of digestible carbohydrates in people with Type 2 Diabetes compared with healthy, non-diabetic individuals.
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.
1.a. Given what you know about glycolysis and gluconeogenesis, does it make sense that insulin activates PDH phosphatase? Why? b.How do vitamins increase to the breadth of chemical reactions available within a biological system?
Consider a 96 kg adult, who is overweight. Weight loss would improve their general health and wellbeing. If 35 % of the body mass of this 96 kg adult consists of TGs (in adipose tissue), what is the total available fuel reserve, in kJ and kcal, in the form of TGs? 2. This 96 kg adult decides to begin a starvation diet to lose weight. They aim to reduce their weight to 75 kg, which will be a weight loss of 21 kg. If the only source of nutrient energy for this 96 kg adult is the oxidation of fatty acids stored at TGs, how long (in days plus hours) will it take for this person to lose 21 kg of their body weight under starvation conditions? The daily energy expenditure for this 96 kg adult is 8700 kJ. This is equivalent to the recommended Australian average daily energy intake of 8700 kJ. 3. Calculate the weight loss in kg/day under such starvation conditions if the oxidation of fatty acids stored as TGs were the…
