A 7. 0 kg (1. 54 lb) adult requires a calorie intake of 2,0. J) of food per.. Two of the following questions will be on the exam Question 1: A 7. J) of food per day. The food is metabolized and the free energy is used to synthesize ATP for useful work. The efficiency of converting food energy into ATP is 5. Calculate the mass of ATP used by an adult human in 2. Recommended Daily Calorie Intake Calculator. Daily Calorie Intake for weight lost, dieting and reduce body fat. Calculate your calorie intake to lose. ATP formula weight = 5. DG'° = - 3. 0. 5 k. J/mol) 2)If ATP is present at 5 m. M inside cells, and if the intracellular volume corresponds to about 2. ATP molecule hydrolyzed and rephosphorylated, on average? Question 2: 1)Write the chemical equations for the three reactions in the citric acid cycle in which NADH is produced, including the enzymes involved. Recommended Daily Calorie IntakeNone of these reactions involves molecular oxygen (O2), but all three reactions are strongly inhibited by anaerobic conditions; explain why. During electron transfer through the mitochondrial respiratory chain, the overall reaction is: NADH + 1/2 O2 + H+ - > NAD++ H2. O Given the following reduction potentials, calculate the standard free- energy change, DG'°, for the reaction. F = 9. 6. 4. 8 k. J/V·mol): 1/2. O2+ 2. H++ 2e- -> H2. ![]() ![]() Ever ask yourself, "How many calories do I need?" Use this simple iBodyFit Calorie Calculator to find out. O E’0= +0. 8. 16. V NAD++ H++ 2e- - > NADH E’0= - 0. V Note that RT= 2. ![]()
How Many Calories To Maintain WeightJ/mol. 3)The measured membrane potential across the inner membrane of a liver mitochondrion is approximately 0. V. The p. H of its matrix is 0. Considering the number of proton ions transported through the mitochondrial inner membrane during oxidation of NADH, show how much energy of NADH oxidation is preserved in the form of electrochemical gradient? What percentage of this energy is converted to produce ATP? ATP ®ADP + Pi DG'° = - 3. J/mol Assume that log ([ATP]/[ADP][Pi]) = - 1. ATP are produced per pair of electrons transported by the respiratory chain. Two transport processes across the inner membrane of the mitochondria reduce the proton motive force. Describe both process and briefly explain how they reduce the proton motive force. Question 3: A liver sample from a rat starved for 4. The hepatocytes were grown in the presence of the fatty acid oleate at 0. Under these culture conditions, the concentration of intramitochondrial oxaloacetate is 5 μmole/liter. When the concentration of oleate is raised to 0.
