Glycerol + ATP →ADP+ 3-Phosphoglycerate: AH = -63.39 kJ/mol and AS = -0.1255 kJ/molk. Based on the information given above, Which of the following statements regarding this folding process are correct? endothermic exothermic Enthapically driven Entropically driven Enthalpically opposed Entropically opposed at equilibrium Exergonic for all temperatures Endergonic for all temperatures

If Glutamate + NH4 --> glutamine      Delta G = 14.2 kj/mol and ATP + H2O --> ADP + Pi               Delta G = -30.5 kj/mol What is true? - overall reaction is non-spontaneous -reaction 2 is non-spontaneous - overall reaction is spontaneous -reaction 1 is spontaneous.

The average adult consumes approximately 11,700 kJ per day. Assuming that the metabolic pathways leading to ATP synthesis operate at 50% thermodynamic efficiency, about 5850 kJ ends up in the form of synthesized ATP.       The average adult consumes approximately 11,700 kJ per day. Assuming that the metabolic pathways leading to ATP synthesis operate at 50% thermodynamic efficiency, about 5850 kJ ends up in the form of synthesized ATP. Imagine that creatine phosphate, rather than ATP, is the universal energy carrier molecule in the human body. Assume that the cellular concentrations of creatine phosphate, creatine, and phosphate are 21.7 mM, 2.17×10-3 mM, and 6.30 mM, respectively. Calculate the weight of creatine phosphate that would need to be consumed each day by a typical adult human if creatine phosphate could not be recycled. Estimate the free energy of hyrdolysis of creatine phosphate under cellular conditions to determine how many moles are required. Use the standard…

What is the final electron acceptor for fermentation?

The AG" of the dephosphorylation of phosphocreatine is -43.0 kJ/mol. Phosphocreatine → creatine +Pi; -43.0kJ/mol When coupled to the phosphorylation of ADP to ATP (+30.5kJ/mol) ADP +Pi → ATP; +30.5 kJ/mol calculate the actual, physiological AG for the following reaction in kJ/mol: Phosphocreatine + ADP creatine + ATP at 37°C, with concentrations as follows: Phosphocreatine = 0.715 mM creatine = 0.566 mM ADP = 0.431 mM ATP = 2.382 mM

Which of the following are thought to be possible explanations for apparent contradictions in the energy balance as it relates to weight loss and the thermodynamic laws? O self reported energy intake and expenditures. O the assumption that weight loss is based on carbohydrates decreases only. O metabolic efficency D over time as weight loss occurs there will be increases in resting energy expenditure.

Draw the cardiac pharmaceutical digitalis to represent the energy form. RO CH3 k I CH3 OH R

Explain why triacylglycerides are more efficient at energy storage (~ 9 Calories/g) compared to the two othermacronutrient classes, carbohydrates, and proteins (each ~ 4 Calories/g). Shown below is a representativeexample of each for comparison.

All are true of the Embden-Myerhof pathway EXCEPT     Question 88 options:   A)  the products pyruvic acid and ATP under aerobic conditions enter the Krebb's (TCA) cycle to produce more ATP   B)  the products pyruvic acid and ATP under anaerobic conditions are converted to lactic acid and two additional ATP   C)  Cells use this pathway when they have no energy needs   D)  Begins with the conversion of glucose into glucose-6-phosphate
