To answer this question, please reference the Problem Solving Video: Free Energy, ATP, and Creatine in Resting Muscles. Suppose a sprinter's muscle tissue contains creatine phosphate at a concentration of 140 mM after dietary supplementation. Compound kJ mol-1 The sprinter's muscle tissue also contains 4 mM ATP, phosphoenolpyruvate -61.9 0.013 mM ADP, and 13 mM creatine. 1,3-bisphosphoglycerate -49.4 creatine phosphate -43.1 Jse the table of the standard free energies of hydrolysis of hosphorylated compounds and the given concentrations to ATP (to ADP) -30.5 alculate the free energy change, AG, of the creatine kinase glucose 1-phosphate -20.9 caction in this sprinter at 25 °C. pyrophosphate -19.3

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.

Write down the energy content in kilo-calories (kcal) from one gram of fat, one gram of carbohydrate and one gram of protein obtained by complete combustion in calorimeter (assume by yourself and show the calculation steps) and by completely broken down in human body in the following table. Please give references.   Complete combustion in calorimeter * Completely broken down in body 1 g of Fat     1 g of Protein     1 g of Carbohydrate     1 g of Mixed Food

You are evaluating the kinetics of an enzyme catalyzed reaction containing 5.5 μM total enzyme and 11.2 μM substrate. At this substrate concentration, you determine that the Vo = 88.6 μmol mL-¹. s-¹. If the Vmax 833.3 mM s the KM is: . == " 30.9 μΜ 10.4 μΜ Ο 124.6 μΜ 234 μΜ 94.5 μM

Estimate the flux (mg/cm2/s) by diffusion of estrogen (a steroid) through a lipid bilayer cell membrane when assuming the diffusion coefficient for estrogen across the lipid bilayer is 10^–6 cm2/s, and that the initial concentration of estrogen in the extracellular fluid is 1 ng/mL and 0 in the cytoplasm.
