Glycolysis is the process by which glucose is metabolized to lactic acid according to the equation C6H12O6(aq)2C3H6O3(aq) G=198 kJ at pH 7.0 and 25°C Glycolysis is the source of energy in human red blood cells. In these cells, the concentration of glucose is 5.0103 M, while that of lactic acid is 2.9103 M. Calculate AG for glycolysis in human blood cells under these conditions. Use the equation G=G+RT In Q, where Q is the concentration quotient, analogous to K.

The acid-catalyzed hydrolysis of sucrose, C12H22O11 + H₂O + H+ -> C6H12O6 + C6H12O6 + H+ is known as "inversion of sucrose" because the angle, a, by which the solution rotates polarized light changes from positive to negative as the reaction proceeds (data from 30 degree C): t/hr a 0 78 2 71 4 12 18 24 42 65.10 44.60 32.40 22.45 2.30 48 -1.96 61 -9 86 95 -15.80 -17.25 -21.15 ∞ Use this data to show that the reaction is first order and determine its rate coefficient (at 30 degree C).

In one of the steps in this pathway fructose 1,6-biphosphate (F1,6BP) is converted to gylceraldehyde-3-phosphate (G-3-p) and dihydroxyacetone phosphate (DHAP). This reaction is catalyzed by the enzyme aldolase. For this reaction at 25 celcuius and Ph7 we have: Keq= 10-4M and Delta G = +5456 cal/mol Calculate the following: The concentration of F1, 6BP, DHAP and G-3-P at equilibrium when the initial F1,6BP is (A) 1M, (b) 10-2 M, (c) 2 X 10*4 M and (d) 10-5 M. I been trying to solve this problem but I dont even know where to begin with. Atleast help me with problem A, I would be able to guide myself through.
Sucrose is oxidized according to the following formula. C12H22O11 + O2 → CO2 + H2O You are investigating cellular metabolism in vitro. Under your experimental conditions, you plate 12 million cells in a dish using 10 ml of cell culture media. You grow the cells in a special instrument that can measure metabolic gases. After 24 hours, you instrument has detected that 28.8 mg of oxygen have been consumed and the same mass of carbon dioxide released. Your previous tests have shown that these cells consume 75 μg/106 cells-h. (a) Determine the limiting reagent, (b) percent excess of the other reagent, percent conversion for both reactants, and (c)extent of reaction (ξ). (d) Your initial concentration of sucrose in your cell culture media is 13.0mM. Your instrumentation can only resolve sucrose concentration at 0.1 mM increments. Can you detect the change in sucrose concentration with your instrumentation?
An enzyme catalyzed the reaction: S -> P has a AG" value of +4.8 kJ/mol. If you start with a solution containing 500 mM substrate [S] prior to the addition of enzyme and initiating the catalyzed reaction, then what is the substrate concentration [S] after reaching equilibrium? [R = 8.315 J/ mol* K; T = 25 C] NOTE - Provide your numeric answer in mM units as a TWO digit significant figure, and do NOT include units in your answer (report the numeric answer ONLY).
