During a 20-minute workout, a person burns 350 calories. What is the number of grams of glucose undergoing glycolysis in muscle cells with ample supply of oxygen? NADH in muscle cells is transported via the glycerol phosphate shuttle (which byhpasses Complexes I and II of the ETC). The human ATP synthase has 8 c subunits. Take note: Molar mass of glucose is 180 g/mol 1 calorie = 4.184 J phosphorylation potential in muscle cells is ~55 kJ/mol
How much fat (in grams) would the body have to burn to produce the daily minimum requirement of 40 kg ATP from ADP and phosphate? Assume that: 1. The fat is metabolized completely to water and carbon dioxide. 2. The energy that is released can be used entirely for ATP production. 3. Complete oxidation of 1 g of fat to water and CO2 releases 9 kcal or 37 kJ. 4. The Delta G for ATP hydrolysis is -30.5 kJ/mol. You will have to look up one more value online to answer this question, but you do not need to know anything about lipid metabolism. A) approx. 16 to 17 g of fat B) approx. 65 to 66 g of fat C) approx 22 to 23 kg of fat D) approx. 267 to 268 g of fat E) approx. 5 to 6 kg of fat
Each Mole of ATP formed from ADP + P conserves about how much Kcal energy ?
A 70-kg adult human (154 lb) could meet his orher entire energy needs for one day by eating 3 moles ofglucose (540 g). (We do not recommend this.) Each mol-ecule of glucose generates 30 molecules of ATP when it isoxidized to CO2. The concentration of ATP is maintained incells at about 2 mM, and a 70-kg adult has about 25 litersof intracellular fluid. Given that the ATP concentrationremains constant in cells, calculate how many times perday, on average, each ATP molecule in the body is hydro-lyzed and resynthesized.
Since ancient times it has been observed that certain game birds, such as grouse, quail, and pheasants, are easily fatigued. The Greek historian Xenophon wrote: “The bustards . . . can be caught if one is quick in starting them up, for they will fly only a short distance, like partridges, and soon tire; and their flesh is delicious.” The flight muscles of game birds rely almost entirely on the use of glucose 1-phosphate for energy, in the form of ATP . The glucose 1-phosphate is formed by the breakdown of stored muscle glycogen, catalyzed by the enzyme glycogen phosphorylase. The rate of ATP production is limited by the rate at which glycogen can be broken down. During a “panic flight,” the game bird’s rate ofglycogen breakdown is quite high, approximately 120 mmol/min of glucose 1-phosphate produced per gram of fresh tissue. Given that the flight muscles usually contain about 0.35% glycogen by weight, calculate how long a game bird can fly. (Assume the average molecular weight of a…
How many ATP molecules could maximally be generated from one molecule of glucose, if the complete oxidation of 1 mole of glucose to CO2 and H2O yields 686 kcal of free energy and the useful chemical energy available in the high- energy phosphate bond of 1 mole of ATP is 12 kcal?

It is being said that our bodies cannot produce lactic acid but rather lactate and it's the metabolite summation of ATP, hydrogen, and lactate that cause the burn. But I was taught that lactic acid does not cause muscle burning sensation but instead its the increase in proton concentration that creates an acidic environment but since lactate is the component measured in the blood and blood is strictly a weak base and lactic acid is the corresponding acid and uses muscles as an energy it can help reduce the acidity. So I'm just confused and would like some clarification if our bodies do have lactic acid and what causes the burning sensation in our muscles when getting a pump

The average cell, at rest, hydrolyzes 10,000, 000 ATP molecules per second. You are studying the stem cell population found in the intestinal Crypts. In the intestine there are s total 5 x 1011 cell number. The stem cells have a 85% higher metabolism than an average resting cell. ATP hydrolysis yield 7.4 kCal/ Mole ATP.
