Question: question 14 when our muscles do not have enough oxygen...
When our muscles do not have enough oxygen, glucose is converted to lactic acid to produce energy as shown by the reaction below: C6H12O6(aq) 2C3H6O3(aq) (+ some energy) Glucose Lactic acid a In a particular muscle sample, it was found to contain 1∙20 x 10-3 mol/L glucose and 7∙60 x 10-3 mol/L lactic acid.
Determine the original concentration of glucose in the 10∙00 mL sample? (Assume that only the above reaction occurred). [4 marks]
b A 2∙00 mL sample of blood was tested for concentration of Lactic acid. The sample was first diluted to 10∙00 mL and then 1∙00 mL was tested and found to contain 1∙80 x10-6 mol lactic acid. Determine the concentration of lactic acid in the blood sample. [3 marks]
c In the lab, a 1∙00 L solution containing 50∙0 g glucose was treated with an enzyme that converted all the glucose to lactic acid. Determine the concentration of lactic acid produced.
